The question isn't whether your scores are good enough to be considered for the scholarship, if they meet the minimum requirements, which are listed on the website, they are good enough to be considered. The question is, are these the best scores you are capable of achieving. You want to submit the strongest application you can. If you feel you can improve those Reading and English scores with better prep focused in those areas, by all means, do so. You still have lots of time to prep and re-test. If you studied diligently and focused on those areas already and believe this is the best score you can achieve, go ahead and submit it. I believe your Math and Science scores will be weighted more heavily, but everything is important. This advice goes for all parts of your application; don't ask if it is good enough to be considered, ask if it's the best you are capable of. After all, you don't want to be considered for the scholarship; you want to be awarded a scholarship.
