<p>I agree with @DrSteve and @medicsz. Also 1-3 hours a day sounds like too much. I would aim for one section a week where you study all of the problems that you missed. That should take ~2-3 hours per week total.</p>
<p>Its a good idea to set a pace that is not too fast. Studying for the exam is actually kinda fun if you take it slowly and learn a little at a time. But if you go too fast, its easy to get stressed out and want to quit. That’s the worst.</p>
