I'll add this too. Don't be afraid to speak up and ask questions, even seemingly stupid ones.
For some reason a lot of people in UPT, myself included, get weird there. We forget it's supposed to be a training environment and focus more on the competitive aspects. Then we get this weird idea that we don't want the IP to know that we aren't sure of something or we might be making a mistake so we just stay silent about it and hope it goes away or works itself out.
If that's you dude, speak up. You might get lambasted once or twice for weak GK but often you will find the concepts you struggle with, or the things you have difficulty retaining, so did many others. Even something simple like an ops limit, speak up. Maybe that IP also struggled memorizing that number and he will tell you a stupid limric or story that will make you laugh, but guess what, you'll never forget it again . Furthermore, better to nip those lose ends in the bud when they expose themselves to you early, than to let them build until the end of a block or a check ride. If you get to the end of a phase and still have basic questions you are never going to catch up. Ask questions early and often. People have way more patience for stupid questions with a week 3-4 trainee than with a week 20-21 trainee.
I dunno. Maybe that's common sense but for me it took like 6 years in my career to figure that out and I looked like an ass every flying training program i went through.
