Here it is, the last post in this semester. I know you're gonna hate me for this, but I couldn't resist it :D So, below you can see a nice set of words, some of which should really be called determiners rather than adjectives (no matter, really), but more importantly, words which cause a lot of confusion and frustration to learners of English in Poland and elsewhere. The list is not VERY long, so perhaps you will manage to take it in before you forget about studying for the summer.
There is one more thing I want to ask you, more important one actually. I do this every year, so why not now: PLEASE spend some of your holiday time reading books. It doesn't even matter what they are, it might be pretty lightweight stuff, but do give yourself this luxury of sharing another person's thoughts and ideas, diving into an author's mind, and stretching your imagination. Choose something that you know will be rewarding for you, something that will let you forget about everything that is going on around you. Don't you love this feeling?
It would be excellent if you chose a foreign language book - Spanish, French, Italian, English, whatever works for you. But if you've had enough of that and would rather read in Polish, fine! You know what our first post-holiday English lesson is going to be about, don't you? ;)
Good luck with all your exams, and then have a wonderful, relaxing summer, full of new experiences and inspirations!
