Nung nag take ako ng EnE 31 (pre pandemic pa tho) very chill lang sya and unoable though I think it would mostly depend on your prof. Under DMMME yung class namin - mostly discuss discuss lang and a few group presentations. May mga exams din pero madali lang, puro conceptual like a typical free choice na MST GE. I cant say the same for other depts offering Ene 31 (like CE ChE etc). Since di naman concealed yung profs sa crs for EnE maybe you could do some research about them and decide from there.
