You are at square zero so just try and take on all opportunities with an open mind and don’t be afraid to ask questions, people will always want to help you if you have a positive attitude. Although doing a placement may seem like adding a year to your studies, it is worth it. As much as you learn what you want to do, you also learn what you don’t want to do which I think is also really important. The skills you gain, exposure to real-world problems, then all the people you meet will really help you stand out when looking for the next step after university.
