I really need help, my ADHD is crippling me?

I'm a junior in high school. I have an IQ of 137, according to the WEIS-III test, but I'm getting Bs in a couple of courses. I have severe ADHD and Dyslexia, and know that this is somehow contributing to my bad grades.My testing indicated that my Verbal IQ was around 150, but my other form was much lower, around 125 I believe, if that helps on diagnosing this. I just get distracted while at home, and am unable to preform at a superior level. How can I keep focused?

I'm taking Differential Equations, and am afraid that I'll get a B.

Have you considered looking at dietry factors.
Some people have found relief when they stopped dairy products and wheat from their diet.
It`s free, It`s harmless. Try it for say 3 weeks. If you notice any improvement, great. If not you have lsot nothing. That`s how I see it.

obviously you're very intelligent but maybe your just not as good at these courses a lot of people without disablities get b's all the time when their doing their best so I wouldn't worry about it to much however to stay focussed in class I always try to take good notes and ask questions to make the subject interesting and try not to sit by people who distract me!

Obviously you are smart. I would say see a psychologist. There are ways to deals with it but you need professional medical help. This isn't uniqiue, weird, or bad, it is just real, and you can get help.

people without LD struggle to get Bs---its nothing to be ashamed of

what you shoudl be ashamed of is saying that gettign Bs is crippling
