Hello there! 👋
Physics isn’t just a set of formulas—it’s a language for understanding the world around you. When I first began teaching my daughter the basics of Physics, I never imagined it would set her on a path to UC Berkeley’s College of Engineering. That experience reaffirmed for me just how powerful clear, patient guidance can be.
This course is built with that same spirit in mind. Here, you’ll find concise, easy-to-digest summary notes designed to help you quickly revise key Physics concepts before your exams. Each PDF distills the essential ideas, important formulas, and common pitfalls into a format that’s perfect for rapid review and final preparation.
Whether you’re brushing up the night before a test or reinforcing your learning along the way, these lesson summaries will keep you clear, confident, and connected to the beauty of Physics.
Let’s cut through the clutter, simplify your revision, and make Physics both understandable and memorable.
