TSR helped me with a range of things from interview prep, strategically applying to universities, talking things through and getting reassured about even the little things.
In terms of strategically applying to unis, previous application cycle's threads for specific courses and their unis aided us in finding out what that university's selection criteria was, the layout of how they would assess us and things to look out for.
Getting to interact with people in the same position as me really honed in on the fact that no matter how nerve-wracking uni applications are, we're never alone - the community on here is so supportive, informative and friendly.
For interview prep specifically, there was a thread where we could discuss main topics and areas to prepare for and having voices to guide us really made a huge difference. Not only that, it helped me become more confident in my answers and structuring.
Don't know what I'd have done without TSR this year, especially as it was a reapplication!
