Isaac helped with a C++ program that involved friend functions, operator overloading, classes, ostream and istream and more. He quickly understood what the material was even though we work on two different operating systems. He was encouraging and never made me feel dumb for not understanding something. Isaac was a pleasure to work with and I will be scheduling another lesson with him soon.
Nikolay answered very quickly and helped me with an Operating Systems assignment on a very short notice. He is very reliable, so knowledgeable and patient- I wish all my professors were like him! He is now my to-go tutor and would highly recommend him to everyone.
He's also very easy to talk to, and I feel that I have a good understanding of what we worked on together. Would definitely recommend if you need help with an assignment or if you feel like you don't have a great understanding of programming and just want to learn more in general (unfortunately for me, I didn't understand how important data structures was until now, and I wish I'd paid better attention).
