First, please post in normal font color and size-- all this big purple stuff hurts my eyes.
Second, choose whichever topic you like better or know more about.
Third, go to the bookstore and find a text on foreign language testing (there are several in English; I don't know about in Polish); and/or google for 'foreign language testing' -- it produced 1500 pages for me just now-- there should be plenty of sources for you to start with.
Fourth, post your outline here when you've got a plan, and we'll have a look at it.
Good luck.
