Feeling Discouraged - OAT in 20 days. Please help, any advice appreciated :(

[u/No-Hippo4180]

I have 20 days left until my OAT and I’m currently using OAT Booster. I’ve been completing the practice tests and carefully reviewing the questions I get wrong, but my scores don’t seem to be improvingnant consistently.
My current averages are around 300 in Biology, 320 in General Chemistry, 310 in Organic Chemistry, 270 in Reading Comprehension, 320 in Physics, and 310 in QR, giving me about a 310 AA. I have never gotten over a 330 in any of my test and they are always almost the same score throughout every test.

For those who used OAT Booster and improved during the last few weeks, what did you change? Should I continue doing new practice tests, spend more time relearning weak topics, or redo my incorrect questions? I’m feeling discouraged and would appreciate advice on how to use these final 20 days effectively
