I created these notes throughout y12&13 and used them for my A level 2022 exams. I got a grade 9 in GCSE and an A* at a level. These notes were made using the CGP revision guide, edexcel textbook and class notes in order to cover everything in the course. I have also added markschemes from past paper questions and also used the markschemes to help me write the notes to ensure I used the specific words and terminology needed in order to get the marks in the exam. The notes are organised according the the subtopics from the main Edexcel textbook.

If the graph is a curve, draw a tangent at the specified time and find the gradient of
the tangent.
