PhD from Georgia Institute of Technology with thousands of hours of teaching experience

Deadly! He helped me with a Mechanical Vibrations Class assignment that I didn't have time to do it on my own, and I was able to understand the answers to the questions by just reading his work after he turned it back to me (if you know what I mean).
* I got 110/100 on the assignment because of the extra methods he used and the extra use of Matlab to draw graphs that weren't required, he also provided the matlab codes as well, with a clear explanation.
* There was no bonus points added to no one else in the class except for me, because of all the extra stuff he added.
* His handwriting was super neat, clear, and very understandable (it looked like someone who spent a lot of time working on it).
* He was extremely knowledgeable with the subject.
* He promised me exceptional quality and delivered it, or he would return my money back.
* He always checked up on me afterwards, and enquired about what did I score.
* The only downside was that his price was a little high for my budget, but considering the peace of mind he provided me, and the hours he saved me had I ended up doing it myself, I felt extremely satisfied and called it even. Also, if I go back in time I would've worked with him again with a heartbeat.
