HELP.....Introduction to educational psychology CLEP exam

[HiraAliD]

Hi,
(I am a Physical Therapist and need 22 general education credits)

I have to appear in 3 CLEP exams on 20th and 21st December 2016.
Principles of management
Introductory sociology
Introduction to educational psychology

The first 2 subjects are not giving trouble but somehow Educational Psychology is giving me panic attack.....I have taken a couple of prep test but in every test there are 2-3 new (unread by me) concepts .... it feels the subject is HUGE and no matter how much I am prepared there is always a new word, definition, theory or concept which was not in the text books I have studied.....I have the list of topics from CLEP course outline for all three subjects.

Anyone who has taken this exam please tell how much MORE do I need to study as only 20 days are left in exam and is the course outline by CLEP enough to pass the exam.

Any last days tips for Introduction to sociology and Principles of management would be helpful too.

TIA
