Z góry pięknie dziękuję za pomoc

Students often 'compain' (ortog) about too many subjects THAT they have to learn.
If they learned just what they like, they would go 'on' (kalka z polskiego ...wiem, ze idziemy na lekcje, ale po ang. to TO) lessons
willingly. They would be much better prepared for their future
job, if they 'concetrated' (ortog) on particular subjects from the beginning.
When you have THE possibility to check yourself in all 'areas' (moze lepiej 'subjects'), you can easily determine what you are good
at. Sometimes you need more time to get interested in a subject and if
you had resigned from it before you would have 'miised' (ortog) that chance.
