How to prepare for online exam at Novia University of Applied Sciences?

[Auryn]

I applied to Novia UAS during January applications for Bsc in Information Technology in English language. Gave the International UAS exam but didn't pass the minimum points for Maths skills (while I did for Advanced Maths, weird). Actually I had so much anxiety because I haven't been studying Maths for years and forgot many things, plus I couldn't focus because I was in tension all the time.

Anyway, during March they had another opportunity to apply and this time they will select only 5 people. On their website here: https://opintopolku.fi/konfo/en/hakukoh ... ntaperuste it is mentioned that it doesn't have any material to prepare, also asked the uni and they said the same as on the site. I have been looking for information online but don't know how could I best prepare. What would the written exam be about? An essay, maths questions what else?

Thank you in advance for any feedback! It would help me a lot!
