potential useful links for students planning to enroll in organic chemistry

Arrow Pushing in Organic chemistry (~ 7 MB; ~ 300 pages, where only ~ half is content; the remainder are answers to problems)

initial impression: seems to have a systemic development of concept

Everything you need to know about mechanism (~ 1 MB; ~ 13 pages)

initial impression: like use of electron polarity map, but there are gaps in its content

links to additional resources at UT organic chem course website

initial impression: no opinion, since did not explore links

the above links is about "arrow pushing", which maybe helpful in learning organic chemistry - it provides a "logical framework" in learning organic chemistry rather than having to 'memorize' its content. as such, it might make organic chem an 'easier' course for you.
