From my experience, the subjects aren't too difficult if you are keen to learn about it, but theres not a lot of resources to rely on for these subjects in terms of past papers and whatnot cus theyre new subjects. The people who do good in my class are those who go home and code as a hobby. For my school we only have project work for assessments like creating apps and stuff, however it differs for each school. But majorily they all revolve around the same criteria given by NESA. From my friends that take enterprise computing, you do go for work experience like IT support which doesnt sound too bad, but you dont do any work experience for SE. From my knowledge, ENT is more based on business operations like IT support, while SE is very prac and theory based? I think itd be better for you to look into the syllabus of each subject and think about what suits you better tbh.
