This guy is incredibly difficult to understand. Considering English isn't his first language, its understandable but for a Math Class clarity is paramount so this is where he fails. He knows his material though and is a bit cocky.I don't recommend him tho. Not very attractive in my opinion either.

I came in to this Calculus 1 class with a year of calculus already, I made a A+ in the course and never struggled. Will not accept and other algebraic method when solving problems, and counted off so many points. I was told that if I continued to use my same methods I would be forced to drop out, not good at answering questions, will ignore you.

This guy makes calculus way more difficult than it needs to be. Most students in my section received A's in Calculus AB with ease previously and yet struggled for a whole semester in his class. He degrades students for asking questions, expects all work to be shown "his way" or else it is wrong, checks for work on multiple choice exams???

This man has got be hands down the worst professor ever. He made simple concepts of calc 2 seem like they were graduate level math. He doesn't care for you and your grade at all. He offers no drops that would do good to ur grade, no extra credit oppurtunities, and no curves to which you can benefit from. He does not care about his students at all.

While he knows what hes talking about, at least half of lectures he goes on tangents and will try to convince you that knowing the very origins of the math will allow you to magically comprehend everything. He seems to have his own unique way of grading that is extremely work-shown heavy. Hes enthusiastic, but sometimes hard to understand.

He gave a lot of homework but it was an 8 week class so it was understandable. We had an online quiz once a week, 3 attempts, 4 questions. The homework, quizzes and tests were all based on similar question styles so it wasn't confusing. Good professor for the math i took and i will be taking his class next semester.

He is a good teacher. The low ratings are not an accurate representation of his class. The only problem I had with the professor is he is sometimes difficult to work with. Besides that, he is a great teacher, and his exams are like his reviews. He will give points back to you on your exams as long as you show work.

Prof Aparicio explains math simply and in a way that makes it easy to understand. He's funny, a little wacky, and seems to be sort of all over the place, but a nice guy. He will not remind you about online homework, so don't forget about it, it's what killed my grade. The exams are exactly what he instructs in class, just don't zone out.

I took this professor as an online credit for Discrete Math. He's such an excited professor about math and science and loves to teach and answer questions, but only if you go to office hours in person. None of that is conveyed online and he has very few lectures or notes and most of my course was reading the book with little help.

Professor Aparicio is a tough professor but a very sincere one, if he sees you struggle he will make sure to accommodate you and provide help where he can. He is a hard teacher for CALC 3 but if you follow through with his homework and understand his lectures his exams are pretty easy plus he drops lowest grades to help out his students.

Don't let my grade fool you, Aparicio's class is challenging, especially with pop quizzes. He sometimes teaches new topics, then immediately turns them into quizzes with misleading info, like providing an equation and later saying it's wrong. If you have calculus experience, you'll manage, if you don't, I highly recommend another professor.

Aparicio is an okay professor. He could be a little more caring but once you finish his class you understand that he knows what he's doing and is trying to help his students. He will sometimes give practice exams which are extremely useful, but beware he will take away most points on a question if the work is incorrect even if the answer is correct

This professor was one of the toughest graders, and it seemed he sought out to ruin your grade. Most classes had a pop quiz, with one having two. His grading was quite challenging, and he created tests that were more complex than those of every other teacher. Though I got an A, this class ruined my second semester. TAKE ANYONE ELSE OVER HIM.

His lectures weren't awful, but his tests were impossibly hard. 50% of the test was FRQ, and he would randomly take off a random amount of points without reason. Everything on the test was covered by his lectures, but the questions were 5x harder than what he taught in lectures. He does care about his students though.

Prof Aparicio wants his students to understand the content not just answer problems. However, he goes about this the wrong way. Rather than building an engaging curriculum, he opts to single out students and express his dissatisfaction to the class frequently. The lack of a rubric makes understanding his grading difficult.

If you are genuinely interested in math and calculus concepts, Aparicio will be your favorite. He makes Calculus extremely engaging and you'll always be surprised when the class is over.

If you just want the credit don't take this class. However, to discredit this man's passion would be a crime. I believe most of the bad reviews here are from people that are "mad 'cause bad". my grade was an 89, but he gave me an A. He really does see if you are putting in work. Honestly if you cant make it here, you won't make it in later courses.
