Hello! My degree is not even close to computer science, but I can certainly offer my personal experiences with deciding on a university.
Part of my 'luck' is finding exams particularly challenging (I tend to thrive better on coursework), so I have had to undertake a foundation-year; which, in September, I found embarrassing and shameful, but in reality, I have discovered what I truly look for in a university. Now, how does this relate to you?
Throughout my A Levels, I dreamed about studying at Cardiff University. Not only was it close to home, but also a beautiful city, buildings, great course variety and facilities for my chosen subject, and technically a new country (I don't live in Wales haha). And I was so upset when I didn't get in come results day, so had to go through clearing and went to a new university along the south coast. Here, is where I discovered my preferences.
Cardiff was a city-based university, not a campus. I like to describe it as an educational institute you wouldn't know whether you walked in its parameters - I didn't like that, so of course I prefer a campus-based university which is what Newcastle is. I am also aware Cardiff's accommodation isn't 'attractive' compared to other places, and its nightlife is lively, which I also don't like. Drinking and partying does not appeal to me, but that doesn't mean I am boring, I make up for it on other ways by being overly sociable and adjustable. I feel like I would have struggled with Cardiff's nightlife, but you might be great! I personally don't know you.
Now, here is where Newcastle fits in. I am close to finishing my first 'unofficial' year of university, and as much as I have enjoyed where I am at, I do not want to stay. So, of course, I am looking at Newcastle which is the other end of England, and the furthest I may be away from home for a long period of time. Newcastle offers a combined course I am interested in, but also checks several boxes. I am unsure whether I will be eligible to apply, but time will tell.
I understand this may have been a little excessive, but what I am trying to tell you is to consider all aspects. What does Newcastle have that Cardiff does not? For me, it was the course but also it is a campus-based university. Are there societies/clubs/sports you are interested in? All, if not most, universities are different. Is one university primarily exam-based, coursework, or is it mixed? Personally, the less exams, the better. And I could be wrong, but I believe Cardiff and Newcastle have similar rankings, so either way, you are going to a great university. I have not personally done this, but check LinkedIn! You may find some people who have completed the degree you're interested in who you could ask.
Hopefully this has been helpful. I wish you the best of luck in your exams and deciding on a university. It is hard to know what is right, but trust me, you will know if something truly feels right for you.
