You should have already heard that from September 2018, you will need to use your own laptop in computer practicals of the Faculty of Geosciences. And you have received instructions to configure your laptop, to be able to use educational software. If this is not the case, then you can read more about this here.
See the Frequently Asked Questions (FAQ). Here you can find information on when and how you can borrow a laptop from the university, in case you do not have one for example. And what the recommended specifications for your laptop are. If you can not find the answer to your question, feel free to contact Claudia Heres at C.Heres@uu.nl.
