I am not sure about your timetable but they won't really hold important labs around then.. the important things happen near the end of the uni year! I'm going to assume that you should contact the year 1 tutor (Dr John Brazier) to find out more information, I assume that's what you would have to do in order to find out the rough timetable?
The uni arranges day placements at The Royal Berkshire Hospital and community pharmacies around Reading. At the end of third year you also get a hospital/community week placement arranged by the uni, but I'd strongly strongly recommend that you look for placements yourself and apply to as many places as possible, especially if you want to do hospital pharmacy for your pre-reg, it's worth getting some experience by applying around. It looks very good on your hospital pre-reg application.
Read the bit I wrote above as it covers that! Also, yes, hospitals love to see people who have gone out their way to find work experience on their own accord.
I'd say not to get a gaming PC, a laptop is probably a better option?
What about any hobbies or sports to sign up to? It's worth considering that tbh, but if you really want to then for sure you can get a gaming PC. I'm not sure about the uni halls and their policy with their firewall/ports.
They tend to hold end of term tests and they're informal so they have no bearing on your grades or progression throughout the academic year. In fourth year where you have to do your OSCE exams and you need to pass that to pass the year.
They also hold a non-calculator dosing test in first year where you need to pass, but then again I don't know much about first year stuff because they changed the syllabus around alot.
Hope that helped.
