My advice as someone who was in the same position and has just done a year in industry and about to go back and do my final year of CS (UK), is make sure you enjoy yourself and learn how to manage your time as this will help dramatically. Then during this time if you can learn parts of the syllabus, so it's not the first time you hear about it when going into a lecture. Find your niche what interests you, and gets you excited, talk to your lectures about that stuff, that can help later, especially if you get bored or want to go into research. Overall spend time doing side projects, enjoying learning, part taking in clubs and societies and if you find it easy find something to challenge you! If you want to ask me anything more about my experience so far, feel free to send a message (email in bio)
