Reviews of professor Adrian Sierra

Rating: 5.0/5, difficulty: 4.0/5
Mr Sierra really cares about his students and takes his time to answer any questions. It took me 2+ attempts to take Math 114 because Math is just not my subject. Mr Sierra was the one that helped me finally succeed! Recommend to everyone!

He was rude and disrespectful he was no help at all and told me in a meeting there would be no way for me to pass his class and was super snarky and arrogant when emailing me or talking with me in zoom. If I didn't have to take his class I wouldn't have but I have to.
