Lessons

Hello,

We have finally made it! We have more than 300 lessons on The Blue Tree!!! Isn’t it amazing? Just imagine how much you would know if you did them all 🙂

We also have a new editor of the Science Section. Mateusz – my Dear Son – took up this position. The latest lessons in this section are curated by him. I highly recommend checking this part of The Blue Tree.

We are also working day and night (literally) to prepare a practical course in persuasive presentations. If you need to speak in public, it’s definitely something for you. More news to come.

Stay positive, my Dear Student, and see you on our lessons!
