Hey! I'm a first year at Queen's. Some of the above information isn't 100% as unis will vary in what they offer.
We do 6 weeks theory then 6 weeks placement. For this term we're online 3 days a week and on campus one day. Every day is different timing wise and our lectures vary week by week. Typically we start 9/10 and can finish anytime up until 4. Some days we have 4/5 lectures, others only 2.
Holidays for us this year are 2 weeks at Christmas, 1 week at Easter then 4 weeks in the summer.
We do two community placements and 1 labour ward placement in first year. With placements we are allocated a home trust, this is the trust in which we'll have most of our placements but you do need to sign a declaration confirming that you would be able to travel anywhere in NI. I'm from Derry/Londonderry too and I did get Western Trust, thankfully! We do 30 hours per week in first year and community can be 9-5 Monday - Sunday. Labour ward we've been told to expect 12-13 hour shifts and obviously nights and weekends too.
Best of luck applying! It feels like the last year has flown in for me, I was prepping my application this time last year!
