I have many of the same concerns you do, dolphins00. The heat + humidity + polyester, unbreathable uniforms isn't going to be super fun. From my understanding it's pretty hard to flat out fail COT. Even if you fail the first PT test, it's the 2nd one that counts. You'll have a couple of weeks of group PT and individual workouts (if you can find the time) to get in shape. It rained today, and though the humidity is high there is a breeze and the temp dropped a little. It'll be interesting! Best of luck to you both tomorrow!
