Year 12 urgent help please or I'll fail...

Hello there,
It's now March and I'm doing really badly in all 3 of my subjects maths, biology and geography. (I'm getting E's-U's in all 3).
I haven't put much effort into a-levels at all since I've been struggling with my mental health but I know it's my fault entirely for doing so poorly and I do regret it now
However, with our first set of proper mocks coming up in six weeks I have the chance to turn things around.
The problem is we're more than halfway through the year and I've literally done nothing (barely any work out of class, not paying attention in class) so part of me thinks there will be too much content for me to revise in such a short amount of time. Am I screwed then? Is it too late for me to turn things around and get As in these mocks? Was anyone else in this position and are now doing well? If so please could you give me some advice below as I would really appreciate it as I'm in a hopeless situation atm.

For Maths, work through the chapters on here: https://www.drfrostmaths.com/sow.php...2017&term=Main

The truth is probably no to getting A's in the mocks (dependant on the paper, because some Geo papers are ridiculously easy for everyone and some are insanely difficult) but just know that you don't have to get A's in these mocks. Of course, in an ideal situation getting high marks would be great, but given the circumstances just trying your best is the best thing and preparing as much as possible. Learning the content for geography is quite easy when you learn it through examples or case studies, which in themselves are really easy to understand. For example, Vik, Iceland, was my case study for a multi-hazardous environment, but through it I learnt about volcanoes (katla mainly), people's sense of place, glaciers and urban design. So I recommend going through the content and always trying to link what is being said with a case study or example to almost anchor the knowledge because then in the mocks, you can think of an example and you know how that relates to the concept or question so writing about it should be easier. That being said, if you don't get good grades this time around, you can always ask the teacher to help you go through stuff: they are there to help you and they enjoy teaching the subject they're doing, so they'll take the opportunity to help you. Personally, whenever I get a bad grade or mark, I use it to fuel my motivation to better myself because I never want to be associated with that mark again, which is a relatively good mindset to get into because it changes the focuses on the bad grade to what you can do with the grade you got. Good luck in your mocks, and don't stress too much about them, they are only mocks! ☺️
