He's funny, which keeps the class interesting, but he messes up often when instructing, which makes it frustrating while taking notes. Otherwise, tests are typically fair as long as you go over your notes that you take in class, which are worksheets that he hands out. It's not a bad class at all.

Great guy. Each class we'd have a worksheet to do in groups instead of homework. For tests you could bring a notecard with whatever you want on it.

I may have got an A- from this class this semester, but to be honest, I am still unsatisfied...

He's a good prof. ONLY if you've taken calc before, not easy regardless. He crash courses Calc in a 1.5 hour lecture at most and assigns a graded worksheet after. Optional homework, allows calculators and an index card on tests, though no curve. He's straightforward and doesn't seem to be a bad guy, but this class structure is flawed in my opinion

Professor Dela Pena is not the best, but for calculus , there are professors at Mason who are much worse than him. In class worksheets are worth an exam grade and are usually pretty easy to get an A on. There are three exams and a final which are pretty well represented by the study guides. There are also 5 recitation quizzes, 1 is dropped.

I had Professor De La Pena for MATH 114 and MATH 213. For both classes, the course was 90% straight lectures and 10% worksheets. The classes are boring, which is expected since it's calculus. However, the lectures do explain the material very well, the hard part is just paying attention. As long as you pay attention in class, you'll pass

His lectures are pretty boring, but he does explain the material well and in-depth. He is a bit of a harsher grader, but study and follow all the directions and you should be okay. The tests are pretty straightforward, he's not trying to trick you. He posts the lectures online and homework is done in class. He is always happy to answer questions!

3 tests (no cumulative final) and a bunch of worksheets will comprise your grade. No quizzes, no mandatory homework. Lectures are mandatory if you want the credit for the worksheets.

If you have the choice, TAKE HIM! Gives weekly worksheets you do with your classmates--these are a big chunk of your grade and help a lot with learning. This is the best way to give participation grades. He gets upset if you show up late to class or to tests, but otherwise is very respectful. He knows he is here to lecture on calc and that's it.

Grading consists of weekly worksheets (group work), two exams, and a final exam. Exams are straightforward and allows a notecard for them. Clear on what material is on the exam. Not much opportunity to try problems on your own during lectures, but does the problems himself on the board. Calc 3 is difficult, but pay attention and you'll be fine.

Honestly, the professor isn't too bad, he is a good guy who just wants you to succeed. He lectures are about an hour, then gives a worksheet, which is usually about 3-5 questions each. For the exams, he lets you take one 3x5 flashcard with anything on there, and the exam review he gives are harder than the actual exam. Exams aren't cumulative.

Be mentally prepared when you walk in the classroom. Every class has a quiz at the end on the material he covers (i think this is only for calc 2). The TAs who grade are extremely nitpicky.
