Reviews of professor Rudy Castillo

Rating: 5.0/5, difficulty: 4.0/5
I've always struggled with biol courses, but I enjoyed his class! He encourages us to study ahead prior to class so during his lectures, the key points that he explains will be easier or us to understand. He assigns lecture quizzes usually a week before exams so we have things to study from and the online homework also helps a ton! Would recommend!

I had him for lecture and lab, and it was such a good experience because he listens to students concerns and is willing to help out whenever he can. But there are quizzes at the end of every lab and lecture but they're not too difficult.

Said "This is the hardest class you will ever take" and has pride in the difficulty of his exams. I would NOT recommend taking this professor unless you want to seriously challenge yourself. He can be fun, but don't get carried away by his demeanor. Responds to emails but is often vague and inconcise with his answers, loves his presentations.

I was worried about taking his class as I could not find any reviews on him beforehand but, I would gladly take him again! He is very likable and pretty funny and it's easy to follow him along as most everything is from the power points. His tests are challenging but just make sure to study and you'll be all set! :)

Awesome teacher! He fully explains everything you need to know in lecture and lab, helps you out when your confused or stuck, responds fast to emails, and is a very fun teacher when you interact with him.

He's a lot of fun but he is difficult. If you're not going to take this class seriously, don't even bother because you won't make it. Beware the exams!! Study EVERYTHING, no matter what anyone says! I could have had an A but one exam ruined it all for me. If you're taking his lecture, try to take his lab too! Saturday class is his favorite.

Amazing instructor!! Ive been a student at collin for about two years now and professor Castillo has been the best professor yet! He is very caring towards his students. Hes really good about responding to emails really quickly, lectures come straight from his PowerPoints which makes it easy to study at home. Ask questions hes willing to help.

You have to study on your own for this class, he gives lectures but they are straight from the powerpoint, did not really see the point for attending class other than you get a few test questions here and there. Exams were pretty hard but he provides reviews and then always respond through email pretty quick if you have any further questions.

Mr. Castillo was amazing teacher honestly really helped with understanding the topics and creating real world connections to his lectures. I totally recommend taking his lecture and lab together, it helps especially if he says something from lecture that can help during lab.
