There is an abundance of resources on the web. I prefer to offer you selectivity (as in the top part of our page for Study Skills) but...
if you don't mind feeling overwhelmed and if you're willing to do your own "selectivity" an awesomely comprehensive website — with 1700 pages in 55 categories of learning skills — was run (*) by the chemistry students of Wilton High School (taught by Dr. Bob Jacobs) who brought you Links to a Better Education. / In addition, their website offered page-reviews from the classes of 1998-1999 and 1999-2000 (but these seem to have disappeared!) and 2000-2003. Or you can visit their home page and explore.
* According to the Wilton Library Association, "The Chemistry Coach site was formerly maintained by Dr. Bob Jacobs of Wilton High School; he passed away in 2006. This resource, although not being updated, is available through [the Wayback Machine of] an Internet Archive."
