Has anyone used Uplearn? Watch
i've been using uplearn for my a level economics it's quite expensive but imo it's really worth it
but for AS maths have you tried using examsolutions or hegartymaths(?) on youtube, they explain the content really well and you'd be saving yourself a couple hundred pounds
Try the free trial first and see if you like it, you'll really notice how the content just sticks in your head, i didnt do maths but after using the economics one i can guarantee you its worth it, for maths too.
The tutors really are available, someones always online if not, they reply in a few hours ( obviously try not to message at midnight or something, they are human tutors haha they sleep too), but they helped me a lot when i didnt understand questions.
We have a 3-day free trial available - give it a go and see what you think! 😁
