Do you need to take GRE if have already a Graduate degree?

Generally, no, you do not need to take the GRE if you already have a graduate degree. Most programs requiring the GRE for admission are for *initial* graduate study (Master's or PhD programs). If you're applying for a second graduate degree, or a professional program like an MBA, the requirements vary widely by program.

Some programs might waive the GRE requirement if you have a strong academic record from a reputable institution, or if your previous graduate degree was in a closely related field. However, you should always check the specific admission requirements of the program you are applying to. The program's website will explicitly state whether the GRE is required.
