She is an extremely hard professor that does not explain things thoroughly, and so you are on your own. Should not teach higher than 125 or 115. Just about everybody knows she is hard and is not recommended. Drop ASAP to avoid low grade. Hard grader.

Wouldn't take again

By far the worst teacher I have ever had in my 13 years of public education. Talks bad about other students and slanders their political beliefs as well. An absolute monstrosity of a professor in every sense of the word. If there are no other teachers available other than this abomination, just skip the class entirely.

Her lectures provides no assist for her quizzes and exams. Gives out so much homework and just started requiring classwork to be turned in in the last 10-15 min of class; meaning she expects you to complete a number of questions (which some require upload from phone) in a matter of 10-15 minutes. Very strict on Proctorio platform. Non-lenient.

The lectures she provides do not meet the difficulty of the problems she presents in tests and exams. Does not attempt to resolve the question you may have and will provide an answer she deems appropriate to your question. Heavy amount of homework, just wouldn't recommend.

The tests questions were harder than the homework and practice. We copied examples she would write on the board, and hardly taught the math concepts themselves. That's how her lectures were. As a result, the steps are very easy to forget. We would have a lot of homework. Going to office hours won't be enough to pass her class.

If you are planning to take this class be prepared for quizzes every Monday and tests as they giveyou little time to study, so much homework and the practice questions where nothing like the quiz/Test questions as they where much harder, they expect too much if you miss more than 2 or 3 days you will get dropped : quizzes were worth 100 points

Don't take this teacher. She teaches well for stuff that isn't in tests/ quizzes/ or even homework related. God forbid you go online to even try to get the answer for your homework online because she makes you use proctorio FOR YOUR HOMEWORK.

I don't know what's harder or more boring to understand, her lectures that go way too fast, or why I look more like the mailman than my father. Asked us to write down how she could teach better, and took into consideration for only two days. Glad I dropped it, her "examples" made no sense, and at least I don't wake up dreading to go to class.

She uses proctorial which I feel like it is uncomfortable especially when the class is online with live meeting. The professor could have just used Zoom to make sure that the student instead of using proctorial. If you feel comfortable using proctorial while taking online class with her you could do it. This was in 2020.

She does not do a good job in preparing for tests or homework. Despite her lectures being somewhat manageable to follow along with, there is little to almost no student participation. Nothing she goes over lecture is shown on either the homework or tests, so its best to take another professor for this class. Petty too when grading.

Professor Castellon is a great lecturer and was able to make the lessons very clear but her tests didn't reflect the content gone over in class. Despite knowing the content, her grading process made it difficult to receive anything higher than a D on exams. Before I dropped the class, almost everyone, with the exception of 1 student, was failing.

She does well in explaining course materials, the homework does well on reflecting that as well. The issues many people have is that the grading is reflected on her test, 65% of her grading is tests. Most of the questions in the test are not on topic with information given in the previous lectures

Difficult test on the first week, HW on scantron with mostly 100 questions to finish in 3 days, does not accept late work at all, 65% of your grade are tests with questions she didn't go over on a strict time limit. Gave us an opportunity to retake any test but did not tell us until finals when it was too late. Gives detailed instructions, however.

The course material was not too difficult, but this professor's teaching approach made it challenging. While the lectures aimed to explain concepts, the tests were not well-aligned. Unstuck study helped me prepare, but I wouldn't take this course again.

Her lectures are miserable, the way she explains the content is weird and annoying, seems personable but will get weirdly condescending about random things. Probably not the worst math professor at ELAC but absolutely avoid if you're able to.

Don't do it. The tests do not reflect the HW or lessons and contain questions that are much more advanced than anything she covers. I only passed bc I noticed that the test questions were similar to the most difficult questions in the textbook. I took this class years ago (I have my B.S. now) and I'm still traumatized.

FYI: Took this class as a 5 week summer class. She is a nice teacher but tests are way harder than what she goes over in class/homework. We started with 15 students, dropped to 3 and by the end of the class, I was the only student that received higher than a C. She doesn't take into consideration my efforts and circumstances. DO NOT RECOMMEND!!!!!!

Would take again

I did not take math for a while and I failed my first test. But I started to go to SI, office hours, and even extended office hours which helped a lot. You have to put in the work and I recommend practicing problems from the textbook to practice for the tests. I passed that class and she was very patient even though I asked a lot of questions.
