1. Student Comments from CIOS
TA: Overall effectiveness: 4.9/5.0
“He completely cleared up topics covered in this class. He made sure that we understood the concepts.
He gave worksheets that prepared us for the material by making them harder than the tests.”
“He was extremely good at teaching and gave us enormous amounts of resources and help whenever
we needed it, including unofficial review sessions.”
“He made sense and almost everything that I learned this semester was from him.”
“His greatest strength was his unwavering support for us. Night and day, he was there, willing to help
us in whatever way possible. Through GroupMe, classes, office hours, review sessions, and more, he was
there to help us and to guide us on how to work through our material.”
“My TA really went above and beyond for his students and did whatever was necessary to help us
understand the material. He would hold review sessions, add extra office hours, meet with us one on one,
etc. Rafa never hesitated to work a problem to its fullest extent to make sure we knew how to do it, even
showing us little tricks so we could remember the material more completely. He is the reason I passed this
class and now feel confident to move on.”
“He can explain things in very effectively so everyone understands, and he works through practice
problems until everyone understands.”
“Not exaggerating when I say he’ll probably be the best TA I’ll ever have at this institute.”
“If I didn’t have this TA, I would have failed the class, because he taught our class everything.”
“He was the best TA I had this semester and I can only hope I have more TA’s like him.”
“He did his job so well and it is the reason I learned anything in this course.”
