Hi harikan,
So, the good news is that you are in a pretty nice spot!
That said, you do need to continue to find your holes and fix those to help improve your score. Thus, engaging in topical practice is a great way to do so. Let's use quant as an example.
For example, let’s say you want to practice Number Properties. You can do so by answering 50 or more questions just from Number Properties: LCM, GCF, units digit patterns, divisibility, remainders, etc.
After each problem set, it's crucial to delve into the questions you answered incorrectly. For instance, if you stumbled on a remainder question, take a moment to reflect. Was it a careless error? Did you fail to apply the remainder formula correctly? Was there a concept in the question that eluded you? This analysis is key to your learning process.
By carefully analyzing your mistakes, you will be able to fix your weaknesses efficiently and, in turn, improve your GRE quant skills. Number Properties is just one example; follow this process for all quant and verbal topics.
Feel free to reach out with any questions.
Good luck!
