(Also taking the ME PE in April. Machine design depth.) I hear you on retaining information. Seems like i'l do some problems one week and then two weeks later they seem like brand new problems. I really don't think (at least with me) that a chapter by chapter approach with MERM will work if it is timed so that you finish the last chapter right before the exam, leaving almost no time to review chapters that were done two months prior. Maybe I am just forgetful.
Right now I feel that I know "a decent amount" on all exam subjects, at least enough to know where to point in MERM if the exam were held today. (Still would not pass today.) This has come from bouncing around subjects, not necessarily by plan but by not developing a better strategy earlier on. Actually, I think it has worked ok, since it has given me some insight to all subjects and problem types that will be on the exam. The single hardest thing for me has been coming up with a plan and sticking to it. I still struggle with it, even now a month before the exam. Do I go through the MERM chapters problems, then go through the six-minute breadth problems, then the NCEES problems, then back to the MERM end of chapter problems, and then review the six-minute problems again before the exam since it will have been weeks since doing them, and so on. This has been my biggest battle.
I did do the NCEES problems but not as a simulated exam. I was thinking of doing the Lindeburg sample exam tomorrow as a simulated exam. I know it's going to bury me, but at least I will have that initial PE exam feel. How much emphasis are people putting on the results of this exam? I know from multiple people that this exam is difficult, probably longer than 8 hours, and not quite representative of the actual thing. With that being said, is it even worth trying to go back through and understand each and every one of the problems after the exam?
I have also begun writing equation sheets for each subject, but am beginning to think that maybe I need to reference MERM for every problem, even if the equation I think I need is on my sheet. Seems like MERM likes to write critical information in adjacent paragraphs to the equations, instead of small footnotes right next to the equations. This may be safer, if it does not take to much extra time. Like everybody keeps saying, know MERM inside and out! I am thinking that it's probably best for me to know MERM well, than several references ok.
