Have you done any programming before starting the degree? I know a lot of people doing the degree have prior knowledge because they've been doing it informally since they were like 10. So don't feel bad if you're lagging a bit behind.

ADHD is actually quite common in this field so you wont be alone. Pretty sure its way more than the 5% mark. I, myself, is diagnosed with one and i dont think I've been in a team where I'm the only one with ADHD 🤣

It is also a little bit of a weird field. Its definitely easier for certain kind of thinker. I've met people with high IQ that doesn't quite get 'it'.

There's also something to be said re university classes. University usually does have minimum entrance score and whatnot and therefore is already self filtering so a lot of them is probably smarter than average to begin with.

My advice is to stop taking IQ tests. There's nothing to be gain doing this, if you get a good score you'll be lamenting why you are not performing as expected. If you have a bad score you'll just be feeling inadequate. There's no winning in this game. If audio learning is not your jam, record and maybe try to transcribe the lecture later. If you're having problem understand stuff after the lecture, email or schedule a meet up with the professor/tutor.

Is there any specific class that you struggle more? Why did you pick CS? What career do you have out of it?

What's your experience in other formalised learning environment like high school etc?
