Our students love it!
We purchased The Real ACT (CD) 3rd Edition (Real Act Prep Guide), Barron's ACT Flash Cards, and Up Your Score: ACT, 2014-2015 Edition: The Underground Guide. For our students, Up Your Score: ACT, 2014-2015 Edition: The Underground Guide is their hand down favorite. When your students actually enjoy studying, guess what happens to their scores? That's right.
I've been adding this to my smoothies. I am enjoying the product.
