    Rules of thumb

    I fretted over using the "rules" of thumb on the exam. It turned out to be mainly my eyesight causing me problems when I would plot things on the Psychrometric chart more than anything. I love my Psycal program. A pair of reading glasses took care of that. I was concerned when I noticed some of the exams using the air density instead of 1.08 or 4.5. I worked them both ways during the exam just to be certain. In industry, if you think about it, it's like an old truck, there's a half a round of play in the steering. For most work, the guy running the load calculation adds 10% safety, yet, they chose the outside air conditions from the .4% column, the boss didn't like the cfm per square foot and asks to bump up the airflow a little. If I'm lucky (I'm the manufacturer) they were kind to me and rounded up your airlow to the nearest 100 cfm..really, the balancing guy isn't going to balance the unit to 6,152 cfm..I can promise. He's going to get it to maybe +/-5 -10%. and call it done. If he doesn't do the "desktop" balance on you and never look at the equipment. Then, they picked the fan at standard air conditions even though the coil in a draw through position and the leaving air off the coil is 52 degrees. 1.08, 4.5, etc is just fine to me unless your at altitude, even then, it's fairly easy to correct. There's a lot of variables. I've always understood the need to do it right and make sure you've accoounted for everything, but it's not a "Moon Shot". Just my opinion. Thanks kelly I didn't think anything about using the 500gpm delta t, it worked fine for me.
  4. What was your study regimen? My study method I write this in hopes that someone will take away some small jewel of wisdom. If one sentence or thought in my ramblings helps someone, then I’ve done what I set out to do. I’m not saying I done it the right way, but I did it nonetheless. I passed the first time. I don’t consider myself overly smart or intelligent, but I was devoted. “Buy In” You have to have the support of family and friends. It is a long and drawn out process. It’s not something to go into halfhearted, you have to commit to do it, they (your family friends, and loved ones) need to make the commitment along with you and allow you the time you need to do it. You need their support and understanding. Sit down and explain to the ones that matter what is involved and what it means for all of you. You’re going to have to devote a good bit of time to this. Better to over exaggerate the time required than have them thinking it’s just going to be a minor inconvenience for a short time. I basically put my life on hold for almost 4 months to do this. You also have to be realistic. All study and no play..well, that just won’t work either. I studied each night, Monday, Tuesday, Wednesday, most Thursdays for three hours each night. Friday night I took off and spent time with my family. Saturday and Sunday, it was back to the books again at least for four hours with the remainder of the days spent with them enjoying one another’s company. Quality, not quantity Make sure you spend quality time studying. Just because you spend a ton of time “studying” doesn’t mean you will do well. Put down the phone, quit texting, and get at it! I started halfheartedly studying in October or November for the April exam. Once I registered and ponied up the money, I knew I had lit the fuse and it was time to get at it. From Christmas on, I followed the above regimen religiously. Find a good place to study without interruptions. Go to the library, a school, or a spare room at home, but seclude yourself. This allows you to develop uninterrupted thoughts and think things all the way through without distractions. Locking yourself in the bedroom only to be interrupted for dinner, by the baby, by the dog, by the phone, or any other distraction won’t work! YOU DON’T WANT TO DO THIS AGAIN! TRUST ME! Ear Plugs Start early with ear plugs. I know this is weird, but try it. I used them in the exam room and was glad I did. The ear plugs will allow you to develop more focus and concentration, or at least it did me. It cut out the distractions of the library and allowed me to become engrossed in the subject matter. I wished I had started earlier than I had with them. Also, by starting early, you will be used to them once exam time rolls around. I wouldn’t try them the week before only to realize you don’t like them or that you have uncomfortable ones. Plan the work, Work the plan Follow a program. Either go by the MERM study guide and review schedule or develop your own. When I started earlier in October and November, I was making an assessment of my skills and weaknesses. I started by reviewing an exam and seeing what I knew and didn’t know and developed a study guide from my assessment. I can’t say what I did was right or wrong, but this worked for me. I realized that I lacked in every area but HVAC. I focused heavily on Fluids and Thermodynamics with HVAC since I planned on taking the HVAC and Refrigeration afternoon exam. I spent well over a month on Fluids, well over a month of Thermo and spent the remainder of the time equally devoted to statics, dynamics, Strengths of Materials. AGAIN! I am not saying this is the right way to do it. Remember I started in October or November for the April exam, even though somewhat halfheartedly. Make a schedule of your expected study days including a subject to study. Eventually I found that I was spending too much time on certain subjects and would force myself to move on. Remember you need to be somewhat well rounded. Knowing one subject like the back of your hand won’t do you any good. You need to know two or three if possible like the back of your hand and the rest to a “good level of comfort”. The average time to solve a problem is 6 minutes. Six minutes. I can’t say whether you would benefit from trying a sample test early on or not, maybe so. Sit down and try it and see how you do and to get an idea of how quick six minutes goes by, then put the test aside and don’t come back to it until a week or so before the test…forget about it. Time to put the lead to the paper. Get some! In addition to the 500 problems in the sample problems book, and the two sample exams, I bought 1000 problems in thermo, 2500 problems in fluids, 800 in statics, 700 in dynamics. I worked my way through the MERM pretty much on schedule. I would review a chapter and start on the problems. Work the problems. Work the problems! Work the problems!! While you’re working the problems, be tabbing your MERM. Us the MERM, know the MERM, you should be married to the MERM by now! You should be familiar with every reference you take to the exam, but especially you should know the MERM frontward and backward. I think Shaggy on here has an excellent picture of his tabbing method, follow his method. Back to the problems, did I say work the problems? Yes, work problems. I worked everyone in the sample problem book, probably twice! I also worked tons of problems out of the other books I had. I even backed up to my school books and worked problems out of the physics book to build a foundation, then moved up to the fluids, then thermo. The more problems you work, the more methodical/mechanical you become at doing them to build the speed you need...remember, six minutes. See the problem, attack it. Take the given, find the state points, find the enthalpy, the entropy, calculate the work, calculate the capacity, etc. Bang, bang, bang. You see the problem and know exactly what needs to be done, no hesitation, pound it out! The more problems you work, the more the process becomes ingrained in your brain. Putting it all together The two weeks before the exam, I increased my study time. Seven hours on Saturday and Sunday, I also bumped it up to 4 hours per night during the week. You’re getting tired, but push through it, almost there. I took the last couple of weekends to simulate taking the exam. By this time, I had gotten my cart that I planned on using to take my books in and packed it up to take with me to the library to simulate. I did this for three reasons. I wanted to get used to sitting there for 4 hours at a time and depriving myself of water and the bathroom, get my bladder used to the long wait. I also wanted to, at this point; get a better sense of where I was with my timing. Six minutes! I also wanted to get used to using my references under duress to see where the “cracks” were so to speak. What things I needed to add more tabs to, how to manipulate them efficiently and if I thought I even needed the reference at all. There is limited space on the table top, there’s no sense in having something with you and not using it. If you think you need to take something, you can take all you want, just leave it on the floor. One thing to think about, the more references you have the more likely you might be to just start thumbing through them looking for an answer. This wastes time you don’t have! Put it on the floor and come back to the problem if you have time later! Back to the simulation, at this time, if I had looked at my sample exams, I had forgotten them. It was all fresh to me. I worked through the Lindeburgh sample exam one day, then the NCEES exam the next. I timed myself and kept to the time limit. I went back and checked my answers and made a list of where I needed extra help. I still had time to polish on some of my weak spots. I repeated the same thing the weekend before, then by Wednesday of the exam week, I was shot. References These are the references I used. I took several others, but truly did not have time to use them. MERM Crane TP410 Cameron Hydraulic Data ASHRAE books Steam tables Some various school books I bought a spiral binder so I could bind things that I could fold double. I made a small “goto” binder that had items I felt were used on a regular basis. All at hand. It had some electrical calcs, thermo, psychrometric stuff, odds and ends I thought I kept going back to problem after problem. I hope this helps someone. Thanks Kelly

If you want to buy more than one of these, let me know and I'll see if I can work something out on the shipping and trim a few bucks off. I figured everything flat rate boxes. So shipping is about 5-8 bucks. I've also got 2 books for statics and dynamics Schaums Vector Mechanics for Engineers Volumes I and II. I think 1500 problems total for statics and dynamics. If you're interested, let me know. I just didn't figure it would be worth listing. On amazon, one is worth about 5 bucks and the other 14. Thanks Kellly

    I'll be honest, I don't fully understand all aspects or requirements of the LEED certified building, but in my opinion, what I have seen and heard, I find to be somewhat suspect and downright silly. I work for a Custom HVAC manufacturer and some of the LEED requirements for refrigerant quantities (so many pounds per ton) are rediciously low. You can't build a large tonnage custom piece of equipment and meet this one point. I always tell them to go buy a bike rack or buy a waterless urinal, but look elsewhere! A higher end piece of equipment with hot gas reheat, large condenser surface (Low condenser TD / Lower compressor KW), evaporative condensers, large serviceable machines, etc, just can't be built and maintain the refrigerant quantity. It works great for off the shelf package units, but not our type of equipment. We meet and exceed 90.1 energy standards on a regular basis...we design units with variable speed condenser fans, and many other energy saving features that cannot be quantified into a "point". Also, these 2" 95% LEED certified fitlers are crap! They're electrostatically charged to obtain the MERV rating for LEED..It wears off in about a week. You can do just as good with a one dollar can of Aquanet hair spray. Forget this LEED silver and gold stuff. The poor owners of the building get scammed into paying out the yang for a stupid plaque to hang on the wall, when they would be better off buying good mechanical equipment and putting the money into their building envelope. The idea is noble, but I think has been possibly been twisted some to allow some to profit like so many other things. We should strive to build sustainable, long lasting buildings, but some of it seems to be wasteful needless spending. Just my opinion. KS

    NCEES Website and Exam Results

    Depending on what state your from, it is probably correct. Not all states have released the results yet. I believe New York is still waiting and maybe Maryland or Massachussets. Sorry! I know how you feel. It's agonizing. Good luck KS

    Results are starting to get out. How did it go?

    Passed HVAC in Georgia. I rode the roller coaster just as the one post said. I was up one day and down the next. I'd really like to say I was confident, but I wasn't. I felt that the morning was much easier than what I studied for, but that the afternoon was harder. I had concerns about unit conversions and I had concerns about mass flow rates vs industry standard 1.1,1.08, 4.5 cfm delta X. I truly put the time in that everyone talks about. 3 to 4 hours 3 or 4 nights a week, plus 5 or so hours on Saturday and Sunday. Towards the end even more time. I did this from New Years to the test. I probably started even earlier, but did not study as seriously as after I registered for the exam and I knew that I could officially take it. I put the time into it, that's for certain and it paid off. I'm so glad not to have to take time out to study this summer. Good luck everyone.

    Thanks! I'm pulling for the rest of you guys and girls who haven't received your scores yet! I know quite a few of us spent a good bit of time asking questions, commisurating and crying on one anothers shoulder. I appreciate the help everyone gave me on here and the encouragement. This board played a big role in preparing for the exam. KS

    NCEES log-in (onhold) due to uploading of PE results

    So true! Nothing to get in a twist about. Sometimes you have to laugh to keep from crying. But come on, they release Iowa!? I didn't think anyone lived in Iowa except all the people who decide what president we will be electing. I guess Montana will be soon followed by anystatebutmine . Georgia is going to be last because I've checked so many times. There's probably some person keeping track by state of all the log-ins and they're getting pushed to the back of the line based on the number of log ins. It's a conspiracy! LOL

    Taking a realistic look at past release times

    Ok, so who besides me has looked at NCEES this morning to see if there is anything new...More than once...Comeon! they're in South Carolina. They should be open by now...Turn those machines back on....Turn those machines back on!
