How do you know your strengths, and weakness? Practice Test just tell you the category. And how to study without procrastinating?
Try tracking your mistakes in two ways
- Careless (knew how to do the math, but made a small error) vs Knowledge Deficit
Then track by type: algebra, trig geometry, stats
I know it is hard, but tracking every mistake will help.
As far as procrastinating goes, it is best to schedule time each day. Even a half an hour of prep can help.
