There are lots of psychology students about- I often get comments like, "ANOTHER one?!" when I say what subject I do, haha.
I'll number my answers just to make it an easier read.
1. Yes, there are one-on-one tutorials (called Personal Advisor Meetings) but only at the end of every term, more as a progress thing to see how you're doing and if there's anything you're struggling or unhappy with. Tutorials in the strictest sense are the (usually) fortnightly meeting you have with around six to nine other students who have the same tutor as you and can be about academic stuff or work experience or whatever else the tutor decides the meeting should be about. (The system has changed recently, and I know it's different for people in my year in comparison to those in the year below, so I'm hesitating in answering exactly how the system works, but I'm sure you get the idea.)
2. There is no choice of modules for the first two years of study. As far as I can remember, in first year you study Self and Society, Abnormal, Biological, Sensation and Perception, Developmental, Research Methods, Statistics, and Learning and Memory. In second year, you study Brain and Behaviour, Conceptual Issues, Developmental, Personality and Individual Differences, Cognitive, Statistics, Research Methods, and Social. So quite a varied course.
In third year, you have a choice of courses from three different blocks. The first block is the 'popular' one, so they have stuff like Abnormal and Social, the second block is basically neuroscience, and the third block has a mix of stuff such as Gender and Language. You have to choose a minimum number of modules from each block.
Third year also involves doing a group project (which counts for 25% of your third year marks) which is basically running and writing up an experiment- the stuff you learn in research methods and statistics in the first two years goes towards that. You also have the choice of doing a dissertation if you so wish- it replaces one of the other modules.
3. I lived in Tuke, and I will be living in Reid next year. I liked having very 'comfortable' halls for first year- en suite, double bed, etc., but it depends on your budget too (though if you don't live too far away, you could go for a 30 week let in Tuke and it saves about £1000- not bad if you don't mind moving out at Christmas and Easter, as I did). I enjoyed being self-catered, the kitchen is a great socialising space too, and it was a lot of fun.
However, when I put down my choices for third year accommodation, I went completely the opposite way and put Founder's as my first choice and Reid as my second (so basically the cheap, catered halls). The novelty of cooking for myself has worn off and I've realised that I'm rubbish at looking after myself when I have lots of other things to do, so catered next year will work out best for me. Reid is good if you want to be catered but want a bit more luxury than Founder's, and it's an often overlooked choice.
An aside point (as it's a question lot of people ask): ALL of the halls are sociable. There is not one type of accommodation that is more sociable than others. In the self-catered flats, you typically have 7 other people to hang out with, and more people on the same floor- I had an amazing social life in Tuke, despite what everyone says about it being a 'less sociable' hall. Likewise, in Founder's, you get your corridor parties and people make a lot of friends all over the place.
So my advice when it comes to halls is to pick:
1. What fits your budget.
2. What suits your needs cooking-wise- do you like to cook your own food? Do you tend to eat at 3am or at random times of the day?
3. Whether you want an en suite.
4. Whether you're happy to move out at Christmas and Easter.
Hope that helps a bit!
