Need urgent advice on final month of test prep!

Hi! So desperate for your advice on how to proceed with my study plan for my final month pre test.

My test is a month away (Nov 29) and I really need advice on how to proceed with my studying. I started the I’m Overwhelmed plan about 3 weeks ago and I am currently halfway through Module 5 (for math). Vocab I am taking at my own pace, but am currently on group 8 (up to 240 words) as well. I study about 6-8 hours a day, and my studying is primarily going section by section through the math modules, doing the exercises and quizzes, and taking notes in a study guide. I also review quant mountain every other day or so and vocab mountain several times a day. Depending on the module, some I got through in 1 day vs some took me several days. My few practice tests before starting gregmat were ~ 156Q/160V. If I get to 160 quant and 165 V I’ll be happy!

With a month left to the exam, my question is whether I should continue with the I’m Overwhelmed (henceforth “IO” plan or switch over to the 1 month plan. I’ve found the IO plan extremely helpful in breaking down the very basics (I haven’t done math in ~8 years), but I also worry that at this rate, I won’t even get through it all in time which will leave me with important test material that I didn’t cover at all! Not to mention not leaving me any time for timed practice/practice tests, even if I do finish it in time. So I am torn between continuing with the IO plan, which from my understanding gives a more solid and thorough foundation (which I know is key – but how valuable is it if I don’t even get to all of the material), vs switching to the 1-month plan which would get me through all of the material but perhaps not at the same depth? Though I haven’t looked at it so I don’t know. I’m also not sure at which point to start incorporating practice tests and timed practice even if I am not through the gregmat plans.

Thank you so so much for any guidance you can offer. Gregmat is truly a lifesaver and I’m so grateful for your service!
