My philosophy is that personal attention is the answer to helping students achieve. I actually had established my own tutoring service, but found that finding my market was the difficult part...so I'm glad to have Wyzant to do the heavy lifting for me!
I've tutored a wide variety of students, from pre-school to a "boy genius" in high school. I believe strongly in working WITH the material the student is presently studying, rather than burdening him...and you...with a second set of books and materials. I'm also a strong believer in mastering basic skills. I'm appalled by how many 8th graders fumble through multiplication tables or high school students (or even teachers!) who can't spell. Study skills, or course, are also basic to success, and I've had considerable success coaching my students on that.
A typical comment I get from parents of students I've tutored is that they approach their schoolwork with more confidence. Plus, grades go up! I do, of course, have references available on request.
