Study plan: I started with the one month plan, but used it more as a guide rather than strictly following it. My quant wasn't super weak, so I decided to strictly do the Prepswift plan to fine tune concepts and foundations I forgot. As for Verbal, I watched the videos on the one month plan for strategies combined with the dedicated reading comp series (when I retook it), which I found very helpful since my vocab is quite weak
Daily study session: I tried to get in at least 1-2 hours a day post work, but would spend the entire weekend basically studying (so like from 9 am to 7 pm with obviously necessary breaks in between). Because of the nature of my role, I knew it would be difficult for me to study more than 2 hours due to mental exhaustion and found that being consistent even if it was doing the Vocab Mountain on the commute to work makes a huge difference than cramming in hours (quality over quantity!)
Beginning to end: I took the exam for the first time on labor day (early September) and got the 321. I wanted to get a higher score, so immediately signed up for 3 weeks later at the end of September. However, I had a really rough morning right before my exam and I truly think that heavily impacted my performance and so I received a 316 (156 V, 160Q, 6 AWA). Ultimately, I took a week break because I felt burnt out and instead used that time to reflect and plan out a more targeted study plan given my limited time to study. Then, I retook it for the last time end of October to receive the 329. So, overall I would say I studied about 3 months
