<p>GPA is good, what is your M+CR SAT? As long as it’s over 1200 it should be fine. I would apply sooner just to be on the safe side though. If you have a lot of ECs, send in a resume. Wouldn’t hurt to write up an essay and maybe get 1-2 LoR if you have the time.</p>

<p>I would hold out and try to get the recs done ASAP. The committee will start reviewing your app as soon as it’s complete: That only requires the basic app, your SAT scores, and a HS transcript. So it’s better to get EVERYTHING (letters, resume, essay, etc.) together and send it in at once to know that they see everything that you have to offer.</p>
