My son did not pass the Sociology Exam(aug 2019) using Speedy Prep . He was 2 months away from his 16th birthday. This is the response I got from Speedyprep. SpeedyPrep questions are not CLEP exam questions. We teach the facts, concepts, vocabulary, and processes about a subject. The student will have to analyze the CLEP questions to choose the correct answer on the exam. This is why we require that students be 16 or older. Young people are memorization machines, but CLEP exams require analysis to answer. That higher function brain development comes a bit later in the growth process during the teen years.
