SRP

Hey everyone!! Now that JC's start soon( abt 1.5 weeks), I feel like SRP wld be one of the first things that are released, so I'd like to prepared but I have a few qns( the website quite confusing lol)

1. Does aggregate of English and 4 best math/sci include bonus points or not? Normally when I try to look up aggregate includes bonus points, while gross/raw does not, but at the same time on some school website it says there are no grade requirements/ raw L1R5 is 10( like wut), also the aggregate of EL and 4 M/sci only is one limit(6), but there's a graded and enrichment so idk atp
2. Is it school based? Cuz like it seems to be an MOE-JC collab or something, so I wouldn't be meeting or doing anything with ppl outside of my sch rite?
3. What are some past yr projects?
4. Would anyone who's done it before say it's worth their time?
