Soooooooooo .... now you have a confidence problem.To all studs or wings. (or old guys?)
1. My problem is not knowledge
2. or even the finer points of flying the t-34
3. my problem is BAW and SA
4. due to being tense in the cockpit.
I've been a STUD and I've instructed hundreds of STUDs. I've done below average and I've done really, really well.

#'s 1 and 2 (above) will not help much unless you address #'s 3 and 4.
Questions: Are you "good enough" to satisfactorily complete the program?? Have you done well prior?? Are you "afraid" of getting a few bad grades ?? Is this just a slump you're in at present ??? Or has this been your trend since the first time you strapped on the aircraft ???
You've established that you have the "grey matter" to do well --- but are you convinced that you can handle the aircraft ??? You know: motor skills, headwork, being able to take in ALL of your learning, study, and translate it into the cockpit environment --- while not being able to take an aviation "time out" prior to thinking and functioning during a syllabus hop.
There's a bunch of guys a lot smarter than me that didn't get their Wings. They could whip up on academics, but it didn't translate into a smoothly performing STUD in the cockpit. You CAN learn to fly by rote --- I've had STUDs that did it and they still got Fleet Seats ... but they weren't as good as they COULD have been if they had learned to develop some confidence in their ability to see/hear/think/fly/ and chew gun at the same time ... sorry I can't help you more in a "hands-on" fashion ... but that is usually the cause of the effect you've described.
You don't have to be the Ace-of-the-Base to become a satisfactory Naval Aviator. But you do have to believe that YOU can accomplish the mission. Which, in your case, is learning to fly, the Navy way ... if you can; this rough time will pass. If you can't get a grip on your performance at present, you need to re-evaluate your approach to flying. Never give up; never quit on yourself; never say die.
Confidence in yourself will serve you well ... best of luck to you.
