50 questions / day for 6 days a week you will cover UWorld in about 8 and a half weeks. If you don't plan on annotating First Aid from UWorld answers then you can probably do 100 questions a day and knock out UWorld in half the time. I copied the following from the website Medgunner.
"The Study Red-Zone (2 months before USMLE Exam)
Ok so it's crunch time... Hopefully you read my article and took some of my advice.
You should aim for reading your main source 3-4 times through during the red zone. Repetition is key!
Aim for 50-100 questions per day of timed testing across all subjects. This will help you switch thought patterns between subjects and as I mentioned before will help you nail the timing.
Reviewing answers should be quicker and a more focused. You should not be writing notes during this time. Focus on knowledge gaps and reviewing major concepts.
If you have extra time during a day, you can rewatch videos for some of your weaker subjects or topics.
1-2 days before the exam:
Study high yield topics, graphs and charts.
First Aid has a high yield systems rapid review in the back of the book.
Use bookmark tabs to mark 4-5 star topics covered in DIT videos and review those pages.
Review statistics and equations so they are fresh in your mind.
Review your high yield mnemonics (MedGunner Board Prep)"
Yes I would! If you get a question wrong, you need a flashcard for it. Doesn't take too much time, and with spaced repetition, you will learn quickly. Study the cards every day.
But who has 4 months to study (or even 2 months). There are lots of good sounding schedules out there for that time frame but really most people only have 4-7 weeks tops.
