come back advice ?

basically i had some family issues and i haven’t been to school in months and essentially dropped out. but im still entered for exams and i do have aab uni offer and my insurance is bbb from a uni that is very lenient with missing offer grades

i do maths bio geography. i thought i might as well give it a go even if i don’t get the best grades, it’s better than nothing. does anyone have any advice? especially for maths, i really don’t know how you could cram maths.

i am naturally quite academic and i can learn content really fast but obviously it’s really late in the year

i have looked at some stuff it’s mainly a2 level math i genuinely have no idea about.

but yeah please help !!
