Re: Mid-quarter Check in
I think the arrangement of this class is very suitable for an online format and can even be a self-guided class.

Re: Studying From Home
Might be helpful to set up a studying space at home. You could try rearrange furnitures and create a space that you are not usually used to.

Re: Midterm 1 answer key
Does anyone remember if every single question in the midterm were either from the textbook or HW?

Re: How are you studying?
I found it helpful to review HW questions before the exam even if I got them right while doing them.

Re: Textbook Problem 1E.5
If the principal quantum number ( n ) is the same, electrons located in p orbitals are going to be located closer to the nucleus and thus having a bigger shielding effect.

Re: Are there subshells past f?
It seems like "j" is being skipped because some languages don't differentiate between the letters "i" and "j".

Re: Textbook vs Lectures vs Other Methods
I watched the lectures and make notes first, then jump into the homework; if I don't understand something, I use hints and search on the chemistry community or just the Internet. And finally, go to the textbook.

Re: How many points for an A and above?
I would assume an A is the standard 90%, which is 450 points. If you're asking about a 4.0 (A and A+), that's usually cut off at 93% or 465 points. Does anyone know why our class uses this grading system? It seems like it works the same way as the 0-100 system but at a larger scale of points. Don't...

Re: Using a Calculator
Upon reading the comments, I took out the instruction manual of my scientific calculator and realized it has forty built-in scientific constants and does SI conversion.....and there I was, typing stuffs wrong.

I think it's quite important to look at the electromagnetic spectrum and memorize how they compare to each other.

Re: how far in the sapling hw does midterm 1 go to
It seems like randomization has been disabled so midterm 1 covers up to Q19.
