After a few days, when you feel like it, take the bags and the information you have taken with you from the various universities and make a choice. Keep everything that has value to you, and recycle what you don't want. Don't wait too long to do it so you don't forget!
With the material you have kept, underline what most strikes you and helps you to answer the questions you had asked yourself. Do you remember? You had made a list of what aspects were important to find in your chosen university.
If you are hesitating between more than one degree, look at the different study plans for the subjects taught, but especially those of the 3rd and 4th year. This is where you will be able to better appreciate the differences from one degree to the other, and you will be more productive!
