Ah, yes.... the "roommate" who has a question.... we understand *wink* --- well, tell your *ahem* roommate that one method is:
1) Get your hands on as many ITE and previous ITE exams as possible. Get through all of them, preferably more than one time. Read the explanations including why the wrong answers were wrong. You'll start to see patterns. I got through 3 of them and have a total of 5 in my possession -- passed with no issues first try....and I don't think I ever passed an ITE in my residency.
Tell your *roommate* to consider getting their own account to ask questions.....
