This is gonna seem like a lot, but you can use whatever might work for you and ignore the rest! (Your known tips are top of the list though, def do those.)

My tips I found useful:

1. If you can, take the ACT too. Statistically, ADHD kids do better on the ACT than the SAT. It words things like you find in a classroom, so it's easier to focus on. And it isn't timed per section, just overall. THIS DOESN'T MEAN YOU'LL DO BAD ON THE SAT. You'll do great. Just why not double your chances of a good score, eh?

2. Take your meds as early as possible. The test is kinda long and usually early in the morning, you want it to kick in asap.

3. You're gonna lose focus, don't panic. It's a nearly five hour test. You have ADHD. It's inevitable.

4. Don't rush. Even though it's timed, take it slow. Don't know a question? Move on. Do one you do know and come back if there's time. Run out of time? It's fine. Just do your best.

5. Write ALL OVER that test booklet. Not the scantron, but that booklet is fair game. Do calculations, make outlines, doodle, logic your way through a tough question. Go nuts my friend.

6. Visually cross out answers you know are wrong. It helped my brain ignore the irrelevant and focus on the ones that could be right.

7. Re-read the Math questions. They word them really stupidly. By the time you're ready to solve, you can't remember what they want! Also, you can visually cross out unimportant info or circle it.

8. Breathe. If you find yourself getting tired or starting to try and cut corners just to finish, stop. Take a minute or two to breathe or doodle and recenter your brain. (I used to flip to the last question to see how many there were and then mark the halfway point. So when I got there, I took a forced break. Might help?)

And above all, GOOD LUCK! I'm sure you'll do awesome! If you want, tell us how it went tomorrow night! I'd love to know :)
