I just want to say a huge thank you to this tutor! He was patient, clear, and really took the time to make sure I understood everything. The last tutor I used on here was honestly terrible — didn’t explain well at all — so this session was a breath of fresh air. I finally feel confident about the topic thanks to him. Highly recommend!

I appreciated the steps he pointed out to help me understand where I needed to be. He walked through each step and when I was wrong he asked me to show him the actual marks that I indicated, which allowed me to follow along better and see where the mistake was made.

I have been paired up this exact teacher many times when I need help on Chemistry. This teacher does meet my needs but is super super impatient when I am trying to solve the problem. This teacher expects the answer within a super short amount of time before I can even get it to them. This teacher seems just very rude in general.This teacher does not give the student time when they are working the problem out and then gets impatient and gives the student the answer. This is not the best way to go about things because then the student does not actually learn. Thank you.
