I did not have video or voice capabilities and that made it difficult to go through the problems. We only went through a very small amount of problems in the 72 minutes of tutoring. A lot of time was spent trying to type or white things on the white board. Mr. Alphonso was very understanding of the subject and easily helped me through my mistakes.

The time is not enough. For us students who are not able to attend a tutor at campus need more than 239 mins. I will bring this up the campus President. I'm very upset. The COVID19 and the time is not helping.
