You are introduced to calculus in the Further Maths GCSE. If not, it is also in Additional Maths (FSMQ) which is taken at the same time as GCSEs - usually aged 15-16.
Even if you didn't manage to do it then, you are introduced to it again in the first year of Maths A-Level (age 16-17).
There's also the Further Maths A-Level which builds on it more.
If you still manage to fuck up and haven't learnt it by this point, you can still be introduced to it when preparing for undergraduate admissions exams such as the TMUA or STEP at age 17-18.
Stop making excuses and accept you're a brainlet
