Mr. Richard was very enjoyable man and easy to understand. Unfortunately, he was helping me only at the end of my chemistry semester; I wish I could learn about iStudy earlier. Twice when was needed we met in virtual classroom – awesome! He provided the best quality of academic level instruction, stays extra 20 minutes almost every time. We immediately had a great rapport and good communication, which is important for 1-1 and online tutoring. Btw, I had no idea that teaching chemistry online is even possible. Thank you, Richard!
