Do grades in my undergraduate diploma matter when I apply to graduate school?

Or they don’t matter and I only need decent GRE results?

Yes, your undergraduate grades matter. They matter a lot.

Of course grades matter; otherwise, u could have skipped college entirely and just taken the GRE.

Grades are quite important, the GRE is often the least important part of the application.

If not, why am I going to college? Of course grades matter. One doesn’t need a degree to do the GRE, that’s just a form of the SAT all over again.

Got it, thanks guys.
