Last week -I name it hellish week- was the peak time of exams and I had 4 difficult final exams in 7 days. That’s the main reason why I couldn’t publish a new post. Exams are not over yet, but they’ll be by the end of February 4th. That’s all for now and the main reason to get this post published was the explanation of the situation. I hope at least grades would be good. More challenging posts are coming!
