I can't remember how to spell his name, Guerillmo A.? But he was incredible, he was patient, had me try out the problems before helping me. Then he also went over my homework problems with me. I had them completed prior to him helping me. I just wanted him to check to see if they were right, wrong. If they were wrong, he would TEACH me how to do the problem correctly vs just showing me how to do it. He's execellent! I truly appreciated his time and paitence during the session. AND he was funny.
