do you recommend PPI for me to take the SE exam? or you study something else in addition to it? Any tips/suggestions from you will be highly appreciated.
I do recommend PPI just for the sake of the one-on-one with the instructor and collaboration with classmates. Here are some things that helped me:
-Get all your books early and every time you study, lay them out on a desk the size of the testing desk. Put your books in the same place every time. The more you simulate how you will actually take the exam, the more comfortable you will feel. Personally, I separated into 4 stacks: materials (steel, concrete, timber, masonry), AASHTO, design codes (IBC/ASCE 7, etc.), everything else.
-Break up AASHTO into 4 sections: Ch. 1-4, Ch 5, Ch 6, everything else
-Make a binder with helpful cheat sheets. For example, I made a quick-reference for rebar development lengths.
-You need to study every chance you get. I took 1 week off for a vacation about midway through and studied about 400 hours total. You are going to sacrifice a lot of time, but your family and friends are also going to sacrifice time with you as well. Make sure to tell them upfront the commitment you are making. You don't want to have to retake the test and have them go through it again. (That was a big motivator for me)
-If you have a weakness, the test will exploit it. You need to know everything or at least where everything is located.
-Don't bring extra books that you don't need. You will just waste time thumbing through them.
-Make notes in all of the references. I drew pictures. I wrote what page number to go to instead of the section because it's quicker to find a page number. I made a chart of beta values for concrete. if a section called for iteration, I made a table when possible. Etc. Anything that saves you time and brain power will help.
-Leave time to study your weakest subject last. That way, it is the freshest in your mind. But you need to make sure you have enough time to study for it. For me, I left about 1 month.
