The best place to begin is always the official GRE website by ETS. They offer free PowerPrep practice tests, real exam-style questions, and a Math Review PDF that helps you build strong basics.

You might also want to check GregMat’s free YouTube lessons. Many students who’ve cracked 320+ say his teaching style is simple and focused on the GRE format. It’s especially useful for Verbal and AWA prep.

For practicing Quant basics, Khan Academy works well. While it isn’t made for the GRE, its algebra, geometry, and statistics videos cover most of the math concepts you’ll see in the exam.
