At least one person in the world has studied from my notes every single day since 2013. This PCM formula sheet is part of that library.
It covers Physics, Chemistry, and Mathematics for Class XI and XII under the CBSE syllabus. Both years of pre-university study, all three subjects, in one reference. If you are revising for JEE, NEET, or board exams, this is the sheet for that work.
I started sharing notes online as an undergrad in 2013. My thinking was simple: if you have something useful, put it where people can find it, and others should be able to learn from it too. That belief has not changed. Someone in the world has studied from these pages every single day since then. That unbroken streak still matters to me.
