Alex was great on the first question I had. But on the second one, it was extremely difficult. While Alex was trying to prompt me and asking me how to do the next step, it was fustrating because i did not know how to do the problem at all. And so his prompting on what is the next step every single time wasn't helpful. i would have thought once he saw that i wasn't sure how to do it, he would have not given me the answers but explain how to get the answer and show me. again, if i knew what to do next, i wouldn't need his help. alex was really good on the first math problem i gave him but seemed like a diff person on the second problem. oh well.
