Hi nathancjr.
The best way for you to hit your score goal is to score at the higher end of the range of your quant scores rather than to increase your verbal score, because schools would prefer to see a quant score in the upper 40s paired with a verbal score in the 30s or low 40s than a quant score in the low to mid 40s with a verbal score in the 40s as well.
The 6 point range in your quant scores indicates that you likely have some knowledge gaps such that, when you see questions in your stronger areas, you score high in quant, and when the test gives you questions in other areas, you score lower. Also, you may simply have to work on execution and getting questions correct more consistently.
So, to more consistently score at the upper end of your range, you could strengthen your weaker areas of quant and also work on accuracy in general.

Improving Your Accuracy on the GMATAlso, by the way, doing timed practice is not necessarily the way to achieve either of those aims because, by doing all your practice with a timer going, you may not give yourself time to develop skills in the process of answering practice questions. So, be sure to continue to do at least some of your practice untimed.
For some insights into how to use untimed practice to maximize the results of your prep, see this post.
https://gmatclub.com/forum/mastering-th ... 58019.htmlRegarding whether you should go ahead and take the GMAT, clearly there's a reasonable chance that you could hit your score goal, but probably you should prep a bit more before you book a test. The GMAT has a tendency to discover people's weaknesses. So, there's a good chance you'd waste your time and money taking the GMAT at this point. So, I think your move is to figure out which kinds of quant questions you'd prefer not to see or consistently trip you up, work on those by reviewing concept and doing topic focused practice, and keep taking practice tests, including third-party tests, until you're more confident that you'll hit your score goal on test day.
