the content is quite big
so definately as someone said before, do it because you love it! not because you need an extra 2 units.
the assessments requires effort, extra effort; such as 2-3 hours at a university library to find sources and then another 3-4 to sort/ read through them. with that along with your essay writting abilities will give you awesome marks so put in the effort = rewarded with good marks
as in workload just in homework, because there is so much to go through, the teacher logically just cant go into deepth about everything and a strict timetable is needed to complete the course, so homework sometimes just reading, worksheets or question n answer will give you a backorund into what ur learning next lesson or it reinforces/ further explains what you have just learnt. not doing it means you will be left behind at your own expense or if the maj of the class doesnt do it, it just slows everyone down..
overall i quite enjoyed modern... its fairly political tho so be prepared for that. but if you are interested and put in the effort you will really enjoy it
good luck
