@ghong Definitely get someone to help you with it! My friend did this for their GRE initially and ended up actually getting convinced into taking the GMAT and doing really well with that tutor. She said it was expensive, but realllly worth it!
@history_new I got a free consultation about this with a tuition agency, and ended up actually ended up working with a tutor. It's definitely worth getting specialist advice on this, it's a big commitment! Let me know if you want their details Goodluck!
Have you thought about getting help with the GRE? My friend got a tutor for the GMAT and it helped a lot! Unfortunately, I think a lot of the time it's just jumping through hoops with these exams and despite what people think, you can be taught the techniques and what to expect - which tends to be the hardest thing for us. The unknown!
Good luck!!
