^Didn't realise people who were home schooled had valedictories and whatnot, learn something new everyday I guess (in my head I'm picturing a kid getting a word-art certificate from his mum over a birthday cake with their dad taking corny photos hahahaha LOL)
Anyway back to the point, I'd HIGHLY recommend going to your school formal/social/valedictory (we had all 3 in year 12). You might not realise it now, but in 2-3 years you'll be in touch with less than 10% of your cohort (having them on fb =/= keeping in touch...). It's a great chance to get together as a group and party and socialise one last time before the serious study ahead and before many of you split and go down different roads. Sure, you may have the 1 year/5 year/10 year/etc reuninions (or maybe your school doesn't do that!), but it's really not the same as when you know each other really well and have that current comradery as you battle your way through VCE together. Even if you don't have a partner for those events, no one really cares, just go there to have fun with your school mates.
I think staying home to study is a really bad excuse (no offence), taking a night off from the books isn't going to bring down your ATAR and it'll probably do you the world of good. I've been through VCE, and I know how stressed some people can be. And I've seen those people, many of whom we had to constantly beg and borderline peer-pressure into coming, come away from a formal being totally re-energised and pumped for the term ahead. So even if you don't want to go, give it a shot! The worst that can happen is that you realise these events are not your thing (better now than in uni balls, but at least you can say you've been to one!), the best that can happen is you have a really good time and come out of feeling amazing!

Nights like these are nights to remember, and I'd highly recommend going. VCE to me, wasn't about the study, the fkn UMAT, the interviews, the rankings and all that shit; VCE was all about the good times: making sure I'd had a fun time with plenty of fun academic and non-academic memories that I could look look back on and chuckle to myself about. Make sure you have these events ticked off so you have some really fond non-nerdy memories to look back on
