Hi Austeja,
Thank you for your questions! :)
There are no mandatory subjects which you have to take in school or grades which you have to get in order to start studying at Saxion. However, I would advice you to take English as you will study in English and also economics. So that you already know the basics of economics which could help you in certain modules! :)
Regarding the necessary qualities, I would say be open-minded, curious and interested in the Tourism Industry. That's all you need! I was also shy in the beginning but it changed through Saxion. Saxion will help you to develop further and just try to step out of your comfort zone :)
I hope I could answer your questions! Please let me know if you have any other questions!
