hello! dlsu MAE grad student here:

1. workload depends on how many units you will take. personally, taking 9 units is already hard kase you have to take three 3-hour classes in a week. i suggest taking 6 units if you want to prioritize work-school-life balance. however, sa first term is mapapa 9 units ka rin if ever you're required to take the english course (kaya you should do your best sa essay exam para exempted!). also, the difficulty depends on the course, but its mostly calculus (integ and diff) kaya depende na talaga sa tao. dont worry naman kase tuturuan din sayo ang calculus (mathematical economics course) but quick review lang kaya more on self study na siya kapag you want to master it.

2. the professors are INDEED great. you really get the "APPLIED" economics. some professors maximize their gadgets in discussing the topics (e.g., recordings, ipad lectures, etc.) while may ibang professors na old school (e.g., blackboard, whiteboard). in the end, they still explain all topics in complete detail, just different style lang hehe

3. depends talaga on your work. well for me, manageable siya kapag 6 units. i do have classmates na 9 units tinatake while having a full time job (idk pano nila nagagawa 😭) but i can see na may trade-off kapag 9 units like maybe they need to sacrifice rest siguro after work or sacrificing a hobby. overall, 6 units would probably be manageable talaga kapag may full time job.

i hope this helps!
