My Lichess puzzle rating was around 1550, and it is now 1909.

After completing the 15 required rapid games, it increased by 107 points to 1251.

I've gone from a puzzle rating of 1640 to 1761 in the first week. The course is helping me be more disciplined.

The calculation strategy has helped enormously and I'm making substantially fewer blunders.

I'm much calmer in my calculations because of this course. My thinking is structured better.

My biggest problem was calculation. After the course I was able to calculate quicker and deeper.
