Wait, but how do I know if GK Pal's Physiology is a real publication? Maybe I should verify. A quick search shows that there are medical students' circles where such notes exist, but there's no official publication by that name. It's possible that it's a compilation of notes or a local resource. So, in the post, I should address that it's a non-official resource. Also, some students might be seeking it because they can't afford official textbooks, so suggesting affordable options like Open Educational Resources (OER) or public domain materials could help.
