Struggling with AS resits and A2 study...

I did biology-OCR last year and got 93%.
I basically read through a revision guide untill i understood everything and did every past papers learning what key words the mark-scheme liked and disliked.

This year I'm revising alot more, making flashcards on my tablet and then testing myself. Download an app called flashcardspro or something like that. I make flashcards of every page in the book, turning each paragraph or definition into a question. Going through them whilst watching a football match or when i'm on the bus is easy revision. Since your homeschooled as i used the bus i would go through all of them an hour before bed or something. I spend 80mins on the bus a day so i do it then.

For maths last year i did not understand alot of the content in class and when i did pastpapers i would make mistakes and understand the answer but i was not learning anything. One thing undertanding an answer and another being able to use the exact same knowledge in a different question. This year If i don't get something in class I go home and go through the revision guide as i find understanding the theory behind maths helps alot.

I also do AQA and will be doing C1,2,3,4 D1 and S1 in the summer.
After learning C3, core two is easy as its basically the basicis of C3. By now C1 feels like gcse maths.
If i was you i would learn C3 to a A* standard and then go back and do C1 and C2, you will be able to do them very very easily.
Core 4 is something like C3 you will have to learn from scratch.

D1 is a memory test and so is S1.

I self taught myself C3 in the holidays so if you have any questions you can pm me.
If you get stuck post a image of the question in the maths forum, alot of the people on here can do a level maths questions very very easily.

Is all the work actually necessary? Were your problems throughout the whole year or just towards exams; I think that if things just went badly around the exam period then most of the work should already be done and it's just a case of making sure you don't forget everything.

I resat all of my maths modules alongside A2 and I only came back to the AS modules a few months before the exams, and I also resat one of my Physics modules.

Sadly they were My entire year was a mess lol. I may try that idea though, coming back to the AS work later...thanks!
