"part a was what i was most worried about and the practice questions on cwitest.com helped alot more than i expected. did maybe two weeks of consistent drilling and passed first try. still cant believe it honestly."

"i put off studying for probably two months and then panicked about three weeks out. wasnt confident on the fundamentals side at all. what actually helped was going back thru the questions i kept getting wrong and figuring out the pattern."

"was skeptical this site would be worth my time. the mock exams felt close to the real thing though. part a specifically, the closed-book pressure is different from just reading a study guide. it helped to actually simulate that."
