Shayan is a wonderful and extremely patient person. He has been helping my son since last year. He could pass all three classes (Calc 1, 2, 3) with good grades thanks to him. My son J. had a health issue two years ago; he took a break for 8 months and started again. He is now a freshman at CSUF and studying computer science. Shayan is assisting him now with programming (C++). I hope this helps all parents that are looking for the right tutor to hire. Thank you.
