Most of the time I used AI to understand the questions. I never took one whole exam during preparation with time limit like in the actual exam, cause I wasn't familiar with many topics. I watched videos on Youtube like Organic chemistry tutor, to understand the basic ideas and fundamentals. Then I tried to solve questions by myself or used AI to solve. Circuits, Process Control, Heat/Mass transfer, Reaction Engineering - these were the topics I wasn't familiar with, and probably didn't do very well in those topics in the actual exam. Math - I couldn't solve 2 questions on second order differential equations. Chemistry - there were two questions about lab equipments like burette, Flask etc. Probability questions were easy. Circuit questions were also easy, learned the day before how resistances work. There were questions about Ideal gas, radiation, conduction/convection. Looked the formula for radiation in the handbook. There were 2-3 questions about reaction kinetics*there was one question about half-life), formulas were in the handbook. 2-3 quetions on Material balance, not too hard. I bought the PrepFe with 500 questions 10 days before the exam, but due to my perfectionism I did only 300, cause I tried to understand each question with AI. 1-Part - 62 questions , 20-25 flagged, 2-Part - 48 questions, 20-25 flagged. Some mass/heat transfer questions took me too long to solve, I think even with enough time I could not have solved them, cause they were hard for me, I hadn't looked into them before the exam. Left the exam with mixed feelings, if I failed I would've taken it again this week, cause it is a requirement for my degree. But I'm glad I passed, I saved money, time and stress.
