Hi
Mehemmed ,
Here is my honest answer (others might not agree) :
Don't spend any extra money on more books.
Use GMATClub for more practice. This platform has tons of practice questions from different sources.
You will not only get the taste of everything but also get help from all of us.
If you start following our Quant expert (
Bunuel ) , you are done with quant.

Happy learning.

abhimahna Thanks for you answer
Actually, this question bank is free of charge

I need lots of questions seperately by topic.
Our questions bank

different GMAT quality questions. It also has
