Hello,
aparnabansal08, and welcome to the community. If you prefer online, module-based learning, then the Marketplace and user reviews might steer you in the right direction. Many such courses take you bit by bit through the Official Guide, so you will want to get your hands on one if you do not already own a fairly recent edition (2019 or later, since the 2019 edition was the first to include the PQID indices in the back, which makes looking up specific questions much easier). If you are looking for both Quant and Verbal guidance, you can either purchase a single, comprehensive course, such as those offered by EMPOWERgmat,
Manhattan Prep,
Magoosh, or Veritas Prep, or you can split up your Quant and Verbal courses. You mentioned eGMAT already, and that is a resource many second-language learners of English have found especially useful, since it adopts a firm grammatical approach to SC; likewise, for Quant, many top-scorers have found
Target Test Prep or Math Revolution useful. I have read that TTP is even testing a Verbal course, although I am not sure who has access to that at the moment or when the product might expand from beta mode. (You could ask Scott from that company, who often scours the Newcomer forum.) Believe it or not, you can also find a wealth of information on both sections through YouTube, although the video playlists might not be as structured as those you might have access to through a paid course.
A 530 is not a bad start at all for a raw score. Once you learn the ins and outs of the test itself, the question types, strategies, and so on, you should have no trouble topping 650, and with the kind of dedicated study schedule you have outlined, I would not be surprised at all if you reached your target score.
Best of luck to you in your preparation. If you have any questions at any point, feel free to reach out again to the community.
