LITERALLY THE BEST BOOK FOR ADVANCED MATHS PRACTISE. Still remember solving it for JEE advanced and the way it was structured made even the hardest problems seem easy. Every chapter starts with a brief summary of the chapter with about 10-15 illustrations followed by solved examples, exercise(level 1 and level 2) and past year questions. Solutions are given to all level 1 questions. Can't recommend it enough, RUN to get it. ✨✨
