I have to read a lot of text books and articles which are not in Finnish

You have a clear need on which you can base a plan to develop your academic reading skills. Perhaps you could benefit from a reading group which may introduce you to strategies that can make you a more efficient reader. Alternatively, in the <a href=”http://kielikeskus.helsinki.fi/vkk/rr” target=”_blank”>Reading Room</a> on the internet, you will find ideas on how to improve your English reading skills (the website is mainly in Finnish).
