I'm working toward my bachelors and my school has a foreign language requirement. I can fulfill the requirement by passing the Spanish CLEP exam instead of taking two semesters of Spanish. Unfortunately, I'm not a native speaker and actually don't remember much of high school spanish, despite having taken 5 years of it (junior high and high school) 20 years ago. I am hoping that some self-study review will refresh my memory. Any tips on the best way to study? Are there good online test prep or book recommendations?
