Very good tutor. I needed help on my Data Structures course and Mr. Ashik helped me to really understand the data structures concepts really well and much better than my professor. We went over ArrayList and list interfaces. He also helped me to understand LinkedList, Stacks, and Queues really well. I feel very happy with our session and would highly recommend him to anybody on computer science topics.
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).
We worked on Python data structures and algorithms for my assignment. Josh quickly clarified some topics I was having a hard time with, and he gave me really thorough and clear technical explanations. If you need help learning Python and SQL concepts, debugging, or preparing for tests/interviews, I really recommend him. :-) He is very friendly and patient.
