Before you stress about the GRE, ask the real first question: do your programs even require it anymore? Many don’t. Here’s what the test is, how to find out whether you need it, and how to prepare without spending money you don’t have to.
First question: do you even need it?
Many programs have gone GRE-optional or dropped it. Check the admissions page of every program on your list before you register for the test or buy any prep. You may save yourself months of work and a test fee.
Do your target programs require it?
Check each program’s admissions page directly. Many have dropped the GRE; others still require or recommend it. Don’t spend months prepping for a test none of your programs want.
Could a strong score help even if it’s optional?
For a borderline applicant, or to offset a lower GPA, a good GRE score can strengthen an otherwise "optional" application. If it’s truly optional and you test well, a strong score rarely hurts.
How should you prep without paying a fortune?
ETS (the test maker) offers free official practice tools, and libraries have free prep books. Free official practice plus consistent reps beats an expensive course for most people.
Even where the GRE is required, it’s one piece — your statement of purpose, recommendations, and research experience usually matter more. Prepare enough to clear the bar, then put your real energy into the parts of the application that carry the most weight.
