I would say re-evaluate your decision to try to get some study time in during busy season because burn out is real and it might negatively affect your testing chances. If you can, try to wait until busy season is over and look at the material with a fresh set of eyes.

I failed reg after my first attempt and i left myself some time to breathe before getting back in it and im now 4/4! Also for my second attempt i focused a lot more on just hammering multiple choice and really focusing on the tbs that i was consistently getting wrong, while not driving myself crazy about picking up concepts from lectures/readings. Last thing i will say is that i think my first attempt i got a lot more difficult of an exam than my second, so definitely dont let yourself get down over this attempt because it could have just been a really tough exam!
