I have been teaching quantitative (math) portion of standardized tests like GMAT, GRE, SAT, for many years to more than 20 nationalities. Please contact for online tuition.

After taking lessons from me for 2 months, you won't need a calculator anymore. For example, you'll MULTIPLY any two digit number by another two digit number in 10 to 15 seconds it's for sure. Or you'll be able to DIVIDE any big number by any two digit number in less than a minute. Or SQUARE any two digit number in 10 seconds. Try then believe.

I have SHORTCUTS of Algebra, Geometry, Word Problems, any topic that's covered in GMAT, GRE, or SAT.
