Hey! I did the Shadowing Scheme last January, and I absolutely loved it! I did natural sciences, but because it was pretty much organised by the students, I got to have a look at chemical engineering too. I stayed at King's college and it was absolutely excellent. If you're doing physics or maths, I think there's a physics workshop or something, definitely go to that. But in the end, I didn't apply to Cambridge, I decided it wasn't for me, but CUSU really helped me to see this. Feel free to ask questions!
