Here we have a poorly written text with quite a few mistakes:
Why oh why did I do that mistake? Of course the good answer was “interested in”! But I wrote “interested by” instead of. And I had a lot of others silly mistakes too. I know I will fail the test and will have to repeat the course. I should really stop to go out with my friends every evening. I should stay in home and work my lessons. I feel so miserably!
Our task for this workshop is to find the mistakes and write an improved version of the text.
