Hi Faiink,
I think what you are trying to do will be challenging, but I'm happy to provide some advice on how to proceed with your prep.
A great prep strategy is to engage in topical learning and practice. Using quant as an example, let's say you are studying Number Properties. First, learn all you can about that topic, and then practice only Number Property questions. After each problem set, take the time to thoroughly analyze your incorrect questions. This self-reflection is key to understanding your learning process and improving.
For example, if you got a remainder question wrong, ask yourself why. Did you make a careless mistake? Did you not properly apply the remainder formula? Was there a concept you did not understand in the question? Did you fall for a trap answer? If so, what is the precise nature of the trap?
By carefully analyzing your mistakes, you will be able to fix your weaknesses efficiently and, in turn, improve your GMAT quant skills. This process has been proven to be effective. Number Properties is just one example; follow this process for all Quant, Verbal, and DI topics.
