How do I know when to take preptests on the v2 version of sevensage?

Timing seems to be my biggest issue, because when I blind review I do vastly better than during a timed test. What are tips for improving timing or ways to study which improve timing.

How many drill Questions should I put into the auto drill builder, if we are to drill for an hour. I am specifically referring to Main Conclusion: Drill It and it says under this I should drill for an hour.

My study scheduler does not take into account the lessons i have already learned or the prep tests i have already taken. Is there a way to create a study schedule that does take into account these things?
