Warwick Economics

Hello guys As a prospective Investment Banker, I have finally decided to head to the University of Warwick for an Economics Degree. Seeing that university starts in October, does anyone here have any tips on how i can spend my next 4 months in a productive way which will hold me in good stead for Spring Week recruiting and beyond? Any interesting books I could read to learn about IB in general as well as specific divisions? Any and all advice will be greatly appreciated. PS: I am an international student from India so yeah I know breaking into the UK will be extremely hard for me but I am up for the challenge
