I gave William 5 stars because he's the best. He is good at what he does. When ever I was getting into a panic state, William will keep calm and cool as a cucumber.
He takes his time to explain concepts when you don't understand. he will keep working with you until you meet your objectives. I'm happy with my sections with him right now, and will keep working with him. He's one of the most pleasant person I have ever met. Thanks William.

William is wonderful and is always concern about the student doing well on the subject being reviewed. He tries his best to accommodate to the time of lessons when needed.

I have been doing tutoring with William for a couple weeks now and he is amazing at guiding me through the bumpy road of AP Physics. Although communication means can be a bit difficult since I was a newbie to the whole "online tutoring" thing, I realized that it was worth the struggle. Before, I had very little knowledge on the subject and did not understand most of what I was doing. William was very patient and explained every step to getting the solution on the endless problems I gave him, plus he knew every answer without even thinking twice! Even though I have a very tight schedule, he is super understanding about my constant changes in tutoring times. I would highly recommend him to anyone who needs a very polite and helpful tutor for physics!!!

Great tutor, very knowledgeable in chemistry. Though we were in different time zones he was always there to answer my questions and gets back to me very rapidly via email or even a text with a sophisticated and detailed explanation of things I struggled with. I personally recommend his assistance.

What can I say, Mr. William is great! I'm not very good at math, so when I found out that I needed a Statistics class I was terrified. Mr. William is the only reason I passed that class…with an A- no less. He was very knowledgeable and supportive. If you need help with math, look no further!

William's number one asset is patience with his students. He is very knowledgeable in an array of subjects and his the training and experiences to give the student a 360 look into the subject at hand. I will be coming back.
