Sprained ankle-advice please

I'm just wondering how long it will take to be better.
I haven't got the type of sprain where I couldn't put any pressure on it, just that pressure did hurt. It swelled up and now it's 3 days, and the swelling's gone down. I've rested it over the weekend, missed uni today to rest it, and am wondering whether to take another day off uni to rest it some more. I've also got a driving test next thursday and about 3 practice sessions prior to it (and I can't change the date of it, cos it will take forever to get a doctor's appointment, and even longer to get a doctor's letter).
So what shall I do? Rest it even more? How long will it take to get better? Will I be able to play football again by 26th Feb (my next footall practice)? And will it be ok to be driving just 5 days after spraining it, and will it be ok for the driving test?
Any advice greatly appreciated.

How did you sprain it? The most common way is for the foot to roll in.
It's good the swelling has gone down, it should get better soon and you just have to be really careful not to make it worse
You should be fine for driving, but probably want to see how the footie practice goes, take it easy to begin with.
Hope it gets better

Yup, I rolled it in. Read that it's very rare to roll it the other way. Happened while, surprise, surprise, playing football.
