i would advise it. if yuore interested in the subject, it can be easy enough if you are willing to put the work in. 40% of the grade comes from a project, while the exam has topics that are both repetitive and the short course makes it a nice subject. people either love it or hate it, but its probably one of my favourite subjects. relatively low maintenance subject, no study required other than exam papers. i would advise talking to the teacher of wherever you are thinking of doing it, they will give you a better undertanding. looking at your profile, i can see you're a sixth year, so take that into account as you have a matter of weeks to get the project for LC 2021 done, and to get the course started and finished. if you're a sixth year doing LC 2021 and not planning on repeating you could be giving yourself unneccessary stress. hope this somewhat helps ;)
