It was a difficult written test

I was intensively preparing for a difficult exam in mathematical analysis at prof. I. Kluvanek at this time 30 years ago. With similar feelings of the happines from learning, I was preparing for the Power BI exam at the beginning of this January. I don't remember exactly the result 30 years ago (but I didn't have to repeat it) but it was just a small step on the way of discovering the beauty of mathematics. However, what I know for sure is that the level of knowledge in mathematical analysis has remained low after the first and second years of studying and is approaching zero just now.

I also know with certainty that intensive learning and testing more and more details from the secrets of Power BI still brings me great joy and pleasure. The level of knowledge is now rated by Microsoft as a lieutenant (the badge has two stars) with the title Microsoft Certified: Data Analyst Associate.

Each difficult test evokes a scene from the movie "Marečku, podejte mi pero!" - "It was difficult test .... difficult ... I had to make a great effort myself too ..."
