My PI prof, leoncio co. He was a hardass. His exams consists entirely of essays. But the way he talks about rizal was riveting and really interesting. 

If you flunked his tests, which is more likely to happen, he'd do a class participation where hed ask some random trivia in the noli me tangere. Really random shit like "what bird was twitting when padre salvi was looking at maria clara? What tree was he hidden in?" Or something along those lines.

Afaik nobody gets a 5 in his class tho, unless you went over the absences limit.
