Is it possible to get a 14-point increase in 20 days

I gave a mock today and scored 311 V151 and Q160.
I only do verbal in greg’s 2-month plan and I just finished the 6th-week.

Previously my mock score was 312 V150 and Q162 so I essentially dint have any improvement.

I dint do any math at all and I am not sure where to start even. I really want to have a concrete plan for Quants. Can someone tell me where I can revise basics quickly (any pdf of formulae). I am not sure I want to watch videos in Quants or if I even have the time.

For verbal, my plan is big book (each test one section timed and the other untimed), verbal book timed and official guide timed.

I desperately need a 14-point increase in 20 days. I am not sure if I will be able to do this. Please let me know if I am being too ambitious. If anybody has done it please let me know, it would be a great motivation. Thank You!

I don’t think that’s feasible. One month would be the borderline.
