Middle School Content Knowledge Praxis Exam!

I have to take another Praxis exam tomorrow morning!  After studying pretty hard and doing so well on my last one - I now think that since I did so well on my last one, I don't have to study so hard this time around.  Umm...yeah, I know it doesn't make any sense. 

Last exam covered English only, which is in itself a broad topic - but at least I had some basic knowledge of English literature.  This test covers English, Math, Social Studies and Science.  How is one supposed to study such broad subject matter?  All I can really do is review what I already know in these subjects.

What I've done so far: 

• Checked out from the library and perused two books - What your Sixth Grader Should Know and What your Fifth Grader Should Know.  
• Purchased and took the ETS sample praxis test

I passed the practice test by doing really well in English and Math and getting slightly more than 50% of the Social Studies and Science questions correct.

At this point my game plan is to review my English and Math and then hope for the best with the Social Studies and Science sections. 

Wish me luck!
