End of topic test chemistry level aqa

I have an end of topic test on amount of substance very soon and so I watched videos and did exam questions but for some reason I keep getting the exam questions wrong over and over, it’s like each time the questions are completely different and I have re learn. One thing, math is definitely not my strongest point, ugh im going to fail this test 😔

May I make a suggestion.
Find a few of the questions you’ve got wrong, post them here (along with your attempt) and ask for help understanding them. If YouTube isn’t helping you, guided solutions to whatever problems you are actually attempting will help you.

It’s way too many that I’ve got wrong to post on here but I will be asking my teacher for help

Fair enough, but I would suggest starting asking questions here as well as there are plenty of users on here capable of explaining why a given answer is or isn’t correct.
