Hello,
It seems like you need to work both on Quant and Verb Basics
I suggest you to follow the Manhattan quant book. It gives all the basic quant learning . Later you can start solving questions on GMATcLUB to Improve further
For Verbal, you can go for any course mentioned on GMATcLUB .
Almost every course provide free access for some time.
you can avail this facility and decide which suites you best ..
As already shared in above post , follow a study plan and revise frequently from your
error log on gmatclub .
Revision of already learned topic is equally important as learning a new topic .
start Practicing OG questions available on GMATCLUB to understand the GMAT question level and practice accordingly.
All the Best !!!
