Thanks everyone for your input. The main reason I am looking on line is the community college that is in my area offers only one chemisty instructor she has about a 50% failure rate I dropped last semester at mid-term. because I had a already full load. This instructor has a really hard time bringing things down to the intro level, she told one student " you are going to understand this It is chemistry just do it ". So hopefully I will find something online thanks everyone
