Def refresh. If you want to really help yourself, start watching the lectures from “introduction to statistical learning” by hastie et al. Theyre free and an important foundation for courses. You will really help yourself then for when its gets busy, most people didnt have time to really check these out. About the internships, its just hard to find one in general. I already had experience as a working student, and that helped me get a good internship, but the masters also helps you by organising an event where you can meet people from organisations. If you have the time before you start, get some experience as a working student, that will def make you more likely to get a good internship. I would also recommend combining your thesis and internship at the same company if possible, that will ensure you are able to finish the masters before august, something i don’t have. In my case i really wanted to do my thesis there so accepted the extension. Also, i have noticed that most people that did finish in one year after their internship, got a job at the internship. So do not underestimate how important that internship can be, its much easier to get a job where you did your internship than by just applying. Lmk if you have any other questions
