Come, young grasshopper, and learn the ways of the almighty Math Shack, a dojo where you can go to train your brain. Get ready to fracture fractions, decimate decimals, and conquer congruence in preparation for the ISEE— and all without breaking a sweat. (Well, you might glisten a bit.)
Before you know it, you'll have mastered more skills than you can shake a katana at. Just be careful with that thing. It's not a toy, you know.
