“Before I met Mr. John, I was scoring in the high 400’s in SAT Writing and low 500’s in the SAT Reading. After working with him for months, I scored a 690 on the SAT Reading and a 710 on the SAT Writing. ”

“Mr. Castellano tutored me three weeks before the ACT because I was unsure of my skills on the English section of the test. The results: my initial practice scores of 24, 29 and 8 on the writing, reading and essay section rose to a 31, 34, and 10, respectively, on the official exam.”

“Mr. Castellano is a reliable mentor and an incredible source of motivation. He taught me to step out of my comfort zone and to explore the world around me. He pushed me to own my strengths and accept my weaknesses. He sees potential in all of his students and the helps them strive to be the best they can be.”

“Mr. Castellano helped me get a precious scholarship that allowed me to study in internationally renowned Mathematical Sciences Research Institute (MSRI) in Berkeley, CA.”
