Depends on what you want outta primary. I've have a comm multi inst ticket and got the grades I needed to fly my choice. At least I thought I did. I wanted p3's but my grades got me e2/c2. My point is depending on how the cards fall you might have grades beyond the cutoff for certain platforms. I'm in kingsville now and I couldn't be happier flying the t45. If you end up doing well and you want helo's or maritime then you'll have to throttle your grades accordingly. Everyone else will tell you to do as well as you can b/c in the end it all comes down to needs of the navy. All things considered that's probably the best advice.
