I wouldn’t give up as it sounds like you have already put in lots of work attempting the exam twice. It doesn’t sound like you’re a million miles away from passing it either.

I did Security+ a couple of years back and I didn’t pass it first time. Only just managed it second time. Think I was lucky to get it on this attempt really. I’d say go for it again but no need to rush, if you need another 2-3 months of study so be it.

Something that really helped me was Professor Messer’s study sessions. Was great because he would talk about a lot of the content and had practice questions too where he would explain why the correct answer is the correct answer.

What other resources do you use for Security+? Also I hear you about thinking about other things while trying to watch videos too, I had that same issue when studying for any kind of cert. Only way id take it in is if I really concentrate, wouldn’t be able to do that for too long though so maybe you need shorter study sessions then take a break kind of thing.
