ummm,..Actally prof weiss changed a lot...even though the class material was really hard and prof weiss used to go too deep abt the concepts....and the leactue notes just like directly copy from the text book.....
Honestly, I had a hard time for the first four weeks coz I didnt know wt to study and there were thousands of formulas.... those were not supposed to memorize but be sure to understand them......
The homework and mid-term were acceptable......but each worth 25% for total grade

If u have Ron as your TA, I;m sure its not hard to pass the class or even get a gd grade coz he was willing to help everyone..He explained the concepts very well and he also understood prof weiss super well...He knew what kind of concepts were important in the course...
One more, "mass on the spring" and "why sky is blue" were all abt the class
