Full courses for Algebra 1- Calculus AB

Note taking packets with homework, addition "corrective" assignments and test and quiz "study sheets" with solutions that could be used as tests. Videos are download-able as MP4s if you don't have consistent internet access or don't want your students on the site with the answers.

Could someone look at and comment on the rigor? Glancing at Algebra 1, it looks solid to me. Possibly could use some additional practice problems from a textbook.
