Out of all the tutors today, they were the ONLY one to actually help me with the problem!!!! I got the answer right initially, but not the formula, and no one seemed to want to help with the actual issue I was having, but rather wanted to solve my word problem. So grateful!!!

David goes above and beyond when it comes to explain math. He makes me feel I understand. Also, he uses positive reinforsment when I am doing good by steps by giving me little check marks. He does the process with you setp by step until you udnerstand. AMAZING tutor. !

I had no idea that the problem I was working on needed the answer to be an expression and not a solution as most problems require. David R helped me to understand this and also how to solve this and similar problems in the future. Thanks, David R.

For some reason it takes a really long time to receive typed messages. The board is also hard to use because it doesn't work with touchscreen so you need to use your mouse or touchpad which is difficult.
