Chemistry Lab final exam, CS 151, matlab..

Chemistry lab final exam
the questions were not too hard but i really couldn't remember the answers for 1 question.
-List down 3 rules for breaking octet rules with its specific example for each rule.
i could remember the terms like 'expansion','odd','deficient', but i didn't know how to provide the correct answer..so..i just wrote down what i remember at that time.
to prevent this thing happen next time..here are the correct answer so that i always remember it.
Rules for breaking octet rules:
1. ODD-ELECTRON MOLECULES
e.g NO
2.OCTET-DEFICIENT MOLECULES
e.g BF3
3. VALENCE-SHELL EXPANSION
e.g SF6

CS151
computer and ethics..i hate this course..i don't have any idea why i should assign for this class..
is it because most of Malaysian students that assign for this course score at least A-? but i'm not them. i don't have any passion for this course and that is the reason i couldn't score a good grade for this course..i've tried my best and that's the result..I accept it..

MATLAB
hmmmm...the 1st class was so bored..i prefer ProE class..now, i have to work on matlab..something that sounds really terrible for me because i'm not a mastermind in matlab.
i just can do it with my friends' help. hopefully, after i graduate from Vanderbilt, i could feel that matlab is like using 570 casio calculator.
