I took some clep exams basically for fun and to complete a BS from www.tesc.edu
Analizing and interpreting literature- very easy
Introduction to educational psychology- interesting took some reading
Human growth and development- not bad
Biology- easy but I had AP biology in highschool, A+P, micro ect before
College Mathmatics- easy just algerbra
Natural sciences- easy but I have taken lots of science classes before
I think that nursing school would not accept too many of these, especialy since science classes dont have labs. But it is a good way to fill in arts/social sciences for degree requirements.
