Whether summer grades and repeats count seems to depend on the school, so check their websites or contact their admissions office. No need to hurry though, you've still got a couple of years to figure stuff out.
And wow, those are some pretty good marks so far! Just hope econ isn't your major
Just finished first year and converted everything to OLSAS, but still don't get how they calculate it with summer grades and repeats.
2.3* (fuck econ lol)
Repeated the 2.3* and got a 3.9
You accept/schedule or reject on the spot. Scheduling is hectic on both sides, and it's not like an offer where you can consider. Most people deal with some unpredictability on call day - you do the best you can, double/overbook if you absolutely have to, then do damage control / shuffling later as possible.
It's often ~10 people per spot.
Official waitlists aren't generally a thing, as far as I've ever seen. If there is a waitlist, I doubt you'd be able to find out exactly where you are on it. If you don't get an interview from a place you're really into, it can be a good idea to follow up with them (a couple hours after the calling frenzy has ended), express your interest, and tell them that you'd really like to come in if a space opens up later. People cancel, it happens from time to time.
