I am gonna start from the very basics and move to the advanced level. So it doesn't really matter if you are opening your textbook for the first time or have already solved a few questions, you will still find this video helpful. Before we begin, let me show you what you can expect from this video: 1. we'll be starting with a general overview - what are the important concept formulae you need to know about 2. Next, I'm gonna walk you through EVERY concept EVERY formula, and EVERY shortcut you need- from basics to the advanced 3. I'm gonna solve a few questions using each concept so you know how to apply the relevant formulae 4. finally, we'll be doing some actual past paper questions with step-by-step solutions. now, I have divided the questions in terms of the difficulty level of easy, medium, and hard so feel free to choose your level accordingly.
