I have a pretty tough job and work a minimum of 10 hours per day so I feel you. Studying after work is not pleasant.

I think consistency is key so I try not to let more than 2 days go by without me doing anything.

However, burn out is real and can hurt your score (and health) so I don’t think it’s a good idea to be constantly “powering through” or “forcing” it.

The way I do it is:

1. Feeling well, max energy: full timed prep test or if I don’t have time for full PT I do timed sections. Full PTs are usually the weekend for me.

2. Tired but functional: a timed (ideally) or untimed section only and maybe blind review it the same day. If I didn’t finish the blind review for my weekend PT I also work through that first.

3. Very tired: progress through a blind review of a PT or section I did before that I haven’t finished (just a couple of problems), short drills either timed or untimed, or just review my bookmarked / annotated questions

4. Exhausted: rest - it’s very important to take a break.
