don't let others get to you. you know you have good grades and do well, that's all that should matter. If you do start to get annoyed, show them your report card, then that should clear everything up!

Your teachers should have coordinated that better tbh

Don't worry about it! Your grade is yours, you don't require rewards to tell you you're hard working. It sucks to not be recognized, and sadly that may be for the rest of your life in any career! If they're really concerned, (Or if you're really concerned to defend yourself) show them your report!

That's fine I was in the top 20 of my class, got no awards, but yet u have an 11.78 gpa on a 12 point scale

I've been there, getting good grades across the board (apart from PE of course) and somehow managing to fly under the radar. You don't need awards though, all this hard work will pay off later. Plus it's good training for adult life when you don't get a pat on the back every time you put a bit of effort in, being self-motivated is another good skill to add to what you already have.

Scream it at the top of your lungs

So let me get this straight - they all thought someone else would give you one, so they didn't? Is this part of this whole 'don't celebrate a good performance so as not to hurt the feelings of the poor performers' rhetoric? Must have been thought up by the same idiots who decided that every kid deserves a trophy just for showing up. Those poor kids are in for a big shock when they enter the real world as adults.

Isn't there some way to prove it in your overall record?

Does it really matter what other people think?

All you need is to believe in yourself op. Nothing else matters.
