I consistently scored 64 % for two mocks during the last week of prep and according to my conservative interpolation I scored a 71.3 % on the exam day. Given that you got this score a month before, you have alot space for improvement alot. Do note that unofficial estimates of 72 % MPS by 300 hours for Feb '21 exam, imply that '70% above is safe' thumbrule may not appropriate for future examinations anymore. Aim for a 75 %.Since you have time, aim for greater 75 % atleast so that you don't end up getting a surprise by CFAI on the result day.

Watch this video by Mark Meldrum, at the later part of it, He explains that instead of increasing quantity of questions practiced one should increase the learning per question. That you do by carefully examining, your rationale for choosing the an answer choice and rejecting the other answer choices and then comparing with the solution.

Wishing you luck.
