My name is David and I am currently a student at the University of Arizona as a PhD student in Optics. I will tutor any age and all levels who have a desire to learn. I understand that the state of Arizona is statistically deficient in the math and sciences. I have the passion to change this by teaching with enthusiasm and giving real life examples for better conceptual understanding. Only then, do I give tricks and tips I've the concept is well understood.
I have been tutoring for over twelve years.. I taught over 100 students in mathematics at a high school level as a math teacher at Southgate academy and immediately improved their test scores by mean of 8%. I have helped over 90% of the students I currently been tutoring 10-15 students at Solutions Custmized Education with 3 students that have graduated under my instruction.
