how much to do these a level exams/practicals

i think you have to pay fees if you're 19 or older?

if i was to teach myself biology/chemistry and another a level (i am okay at maths but a level maths i would not even be able to do the first question lol) physics i find easier than chemistry but so boring but i hate chemistry as well but it is needed anyways biology i could definitely get an a maybe even an a* as i love it will always be motivated for it and find it easy, chemistry i am not sure but i will hopefully get an a i will motivate myself and revise revise, the third subject what should i do? i hate english/history/geography/languages/ i would sit as a private candidate and i know there is a lot of practicals so if i taught myself i would save some money so does anyone know roughly how much it would cost to sit?

What you wrote is virtually unintelligible.

Courses vary between £800-£1300 depending where you sit it.

is that cheap for an a level with the practicals as well?
