I've been teaching math, from 3rd grade to AP Calculus BC to SAT prep, for over 25 years. My students often tell me that they finally GET math when I explain it to them. This is because I have a great sensitivity to precisely where their problems or blockages lie, and fine-tune my explanations to reveal the common-sense, intuitive way to SEE what is happening exactly at those points.
Many textbooks and teachers feel compelled to cover so much material so exhaustively that it is hard for students to distinguish what is important from what has been included in the book or lesson merely for the sake of completeness. I can help you to distinguish the key concepts and skills that you need to get from all of the unnecessary extras--and this insight into what is key and what is extra will actually help you not only to get the important parts, but also to do better on the extras!
