### Student Testimonials:

“Thanks SO SO much for the new video series! I was getting really worried that I wouldn't be ready for the Physics B exam and this is exactly what I needed and it was uploaded just when I needed it! Excellent organization and explanations!” — Steve T.

“Hey Dan, just wanted to thank you, you are saving me in my current class, everything is so simple and straightforward, my current teacher makes this way harder…” — Jawad H.

“Hi Mr. Fullerton, Thank you for your outstanding Physics Lectures.” — Jude N.

“What have your lectures done for me? After watching your lectures I now don't feel the need to memorize a plethora of equations, I actually have a strong understanding of the concepts and my formula recall is almost perfect. What helped from your lectures the most was how you began with simple equation applications  and then provided graphical interpretations.“ — Jay G.

“Your lectures are AWESOME!!! Very organized and you hit all the main concepts. Thank you!!!“ — Nikki C.

okay, thank you so much!

It's amazing how you organized and kept all the information so nicely. I Never saw anyone doing projectile motions in such an organized way and same thing goes to collision problem. I really liked how you approached Collision and projectile motion problems. Very ORGANIZED indeed!

Thanks for the sample no. 9 and 10. I got something very similar regarding pulley in the final exam. It was a great review! Glad that i listened to it!
