I'll be taking it around that time too. From what I've gathered, it isn't ideal but you will still be able to submit your primary application and have the scores back by the time most secondaries come out. This means you will still be relatively ahead of the curve for applications as long as you've completed the rest of your application and prepared your secondary essays in advance. For me, the benefit of getting a higher MCAT score definitely outweighs the cost of applying slightly later in the cycle. I'd love to hear some other opinions on this.
