Translation of bilateral

I have started learning only one month ago, that was during the summer holidays, I want to go to Canada for three weeks and then participate in a course. I hope that I will improve it more or less.
I hope that I will have time to go skiing. Maybe it is even better to go at the end of the season. The doctor, however, did not give his diagnosis yet. If I cannot go I will have to find an alternative.
I have made an internship at a law office, but just for two months. Their salary is really bad. Now to my promise to correct your long message. You need to say: 'On Friday' not 'At Friday'.
