I'm taking REG October 1st then retaking FAR on October 30th so that's about 4 weeks to restudy. Don't know what material you're using, but the second time around I'm:
– skipping the Becker videos (pointless since I already wrote down all the notes)
– adding NINJA notes, audio, and flashcards (I took advantage of the promo Jeff has going on: bought the complete audio and got the notes and flashcards for free)
– actually reading the entire book as I retake notes instead of just the highlighted parts
– creating a study guide dedicated to journal entries (convinced myself the answers would come to me during the exam… they didn't)
I agree with mla1169 that starting from scratch is best. If you can pinpoint things you didn't do the first time around/what tripped you up during the exam, that will help you figure out how to re-prepare. I don't know if I'll need the NINJA material for the other sections, but I figured there's no harm in having it just in case. Spending $300 now is a lot better than $1000+ over time to keep retaking the exam. Hope that helps. Good luck!
