I am a CAT teacher with 15 years experience. These notes are made from 2 different textbooks, past papers and resources used in class. The notes are rich in pictures and colour to make it worth your while.
A few pictures are so blurry that the text in them are obscured, but the notes themselves are good and the pictures are very effective.
