I was going to answer this earlier, but I was waiting to see what other people thought. Since no one is responding, I'll put my two cents in.
In a 6.5 week schedule, it is very possible for you to do 14,700+ questions (350 x 42 days). This is more than enough to go through multiple q-banks 4-5x over.
But it all comes to several different factors:
Time - Most important because the majority(I'm thinking) have classes, exams, are going to be in review courses for step what-have-you. And for you to do soo many questions, you also want to get a good understanding of why you got it wrong or why you got it right(if you guessed). Also, some people like to annotate in their FA books while doing questions and guess what this takes....MORE TIME!!
Another important factor:
Level of understanding - If you are at the point where your understanding is good, then you can very easily do 150+ questions per day. But for me, some of the concepts are not there so I may get to do only 50-100 per day.
Bottom line, you just have to find a good equilibrium between studying and questions. Everyones level of understanding is different so its likely that the number of questions vary from person to person.
Just my take. Good Luck!
