To those people with adhd, how did you manage to focus especially on studying?

You don't.
Hope this helps!

Oh, i didn’t ╮(￣▽￣)╭ dunno how i even made it this far

For me I learn super fast I forget super fast.

sometimes I can focus really hard and can go hours studying nonstop but most of the time I don't. ^(￣∇￣")

I have to do homework as soon as I wake up so nothing else has a chance to draw me in. Sometimes I'll go to cafes, too. It prevents me from walking around/talking to my family.
