By far the best professor I've ever had. It's rare to see a professor who genuinely cares about their students learning and progress as much as Prof. Trujillo and he even went as far as to grade the homeworks himself so that he could give us feedback. He did a great job at making tough concepts feel easy to understand. 10/10Rate My Professors ↗

What students say
Original student reviews · all captured dates
The way he teaches this class is strange, but effective. It's extremely focused on the fundamentals and derivations, but he's a good lecturer. He cares about the subject *and* teaching, which is a rare combo. Despite how intimidating the content looks, he doesn't grade very harshly.Rate My Professors ↗
Your grade in this class is based almost entirely on how well you can memorize long equations. Take this class with literally anyone else if you want a grade that actually reflects your understanding of the material. I haven't had a single class here do the same kind of thing and no other fluids professor expects students to memorize this stuffRate My Professors ↗
No textbook, no practice problems. All the theories and don’t care to explain.Rate My Professors ↗
Before the class starts he sent a email says we have to attend the help session twice a week which was not mentioned in the course enrollment website and these help sessions are not listed in the course schedule. AND he said if we cannot attend the help session, be prepared to FAILE the class or DROP the class. Most arrogant Professor ever seen.Rate My Professors ↗
His grading structure basically says your grade is based on one final exam only. Be prepared cause there is no final exam review (He went through all his slides and that is it). LUCK is the only key to success his class.Rate My Professors ↗
