Deciding whether to take the GRE depends on your academic and career goals. If you're looking to apply to graduate programs that require it, then yes, you'll need to take the test. Many schools use GRE scores as part of their admissions process, especially for programs in fields like engineering, sciences, and some humanities.
If the programs you’re interested in don’t require the GRE, you might want to focus your time and energy elsewhere. Also, consider your strengths—if you're confident in your math and verbal skills, the GRE might not be a big hurdle for you. Ultimately, weigh the requirements of your target schools and your readiness for the test to make the best choice!
