Re: Memorizing SI Units
I don't know if this will help you, but in HS they taught us the mnemonic "King Henry Died By Drinking Chocolate Milk Monday Night" (kilo, hecto, deka, base, deci, centi, milli, micro, nano) to memorize the order of the SI units.

Re: How to remember what v is in equations
Like everyone has been saying, the v for frequency is written in cursive and for velocity it is not. If you forget that you can always look at your units: frequency (hz), velocity (m/s).

Re: How are you guys studying for the midterm?
I also would second doing the homework problems if nothing else, because Lavelle has said those questions will be put on exams. But other than that reviewing the audio-visual modules can help really cement in certain topics, along with doing the UA worksheets from step-up sessions as extra practice.

Re: Advice for studying
Doing the audio-visual focus topics before watching lecture really helps so that you already have a basic understanding of concepts before he goes over them.

Re: Textbook Questions and Midterm
Do we only focus on up to 1D on outline 2 or is all of outline 1 also included for the midterm?

Re: Balancing Chemical Equations
Like previously stated, the only time a number would apply to both elements is if it's used as a coefficient (e.g. 2CO; C=2, O=2). So in that example since the 4 is only after the O, C=1 and O=4.

Re: How are you studying?
To answer the question from above the extra practice problems besides Sapling are from the book! He gave them to us under the "Outlines" for each unit on the class website and they're also on the syllabus. I'm pretty sure some of those questions are taken straight from the textbook and put...
