Hey
DCCane10. Not even a MBA1 yet here (just recently was admitted to schools) and mostly sharing some thoughts in case some GRE tips could be helpful (plus GO CANES!), but I think getting your scores up will make a world of difference in accomplishing your career objectives. The GMAT/GRE scores are both far below the averages for many MBA schools (much less the best ones to go into for product/brand management), but also I think the low quant score (with your GRE) will be a concern for admissions on whether you'll be able to handle the heavy quantitative work at business school. The converter tool is saying a 510 GMAT for your GRE score (you might have known this already). Your verbal GRE score is in the range of some programs listed at this link, but your quant is falling short. A higher GMAT/GRE score would also help balance out a lower undergrad GPA.
Since you've taken the GMAT three times it might make sense to do the GRE again (plus GRE averages at many schools seem to be lower (when converted) than the GMAT averages and the quant is seen as relatively easier). Getting your verbal score up to bring up your total score could probably help a lot, but I definitely think you'll need to get your quant score up as well. For my GRE I just did
Manhattan prep books and don't think there was anything special I did besides study for the quant section. There is a wealth of resources on GRE Prep Club and elsewhere online though. For verbal I loved "Word Power Made Easy" (not even made specifically for the GRE but so many words shared there showed up on it) and I also liked the 500 GRE Words on Audible that I listened to on runs and in the car to help with vocabulary. Getting your GRE converted score into the high 600s GMAT I think would help immensely in getting into much stronger schools. I also don't know much about brand management but believe I have seen that companies like the prestigious schools and that may require an equivalent 700+ GMAT score. Will probably take a ton of work, but might be what's necessary for your career goals (but again I'm not super familiar with product/brand management). If you knock verbal out of the park but still struggle in quant then you may consider doing a course like MBA Math. Some admissions consultants have recommended that on here and said that schools look very favorably on it. It's about 30-40 hours of math you'll need to know for your MBA and they send notice of completion directly to schools. That would be if your verbal score is really great and your total is in the school's ballpark and then MBA Math can help alleviate concerns about your math ability. Maybe MBA Math could even be a good way to prep for the quant section on the GRE (not sure what overlap there is though)?
With Round 2 deadlines only about a week away it means you should have a lot of time to get your score up and apply Round 1 next year. Probably not ideal after four tests and it sounds like we're similar age so I know you might be ready to get to school soon, but an MBA is a big (and expensive) undertaking and dedicating the time to get those scores up a lot can provide a much greater ROI and provide a higher chance of getting you where you want to go. Hope this or parts of it was helpful.
