Re: strong or weak acid
You can judge the strong and weak level from the PH value or the molecular structure(see the textbook).

Memorize them is a good way for tests and exams, we did not learn too much about this now.

Re: Energy in lewis structures
When the formal charge is 0, then the energy is the lowest.
You can check it on the textbook!

Re: What does the formal charge tell us?
I think it can judge the ability to loss or absorb electrons, and how many electrons can the atom or group loss or absorb.

Re: Reading the textbook
I think read the textbook is needed if you have time. Our lecture goes really fast and no one can get all the point in the lecture, so reading the textbook and try to understand better is necessary. It is also a good way to review.
