Personally, I liked the work of skillbox. the material is well chosen, everything is explained in detail and clearly in video lessons. The curators also evaluate the tk perfectly, they always tell me where and how I made a mistake and how to fix it, give ideas, help, and mentor. Everything is also great in tg chats. the guys are responsive and give quick answers to questions.
I recommend it from the bottom of my heart, the interface is user-friendly and intuitive, which is very pleased, so it's feedback, they quickly and clearly explain that they did not understand.
I liked the approach to service, they lead from beginning to end. I will definitely recommend it to my friends and family.
I took a POWER BI course - for use at work. To be honest, I didn't even expect it to be so interesting, and most importantly effective. All lectures are clear, you can use them at any time. The curator always answered all completed tasks the next day, and if something turned out particularly well, he did not skimp on praise. If you asked a question, you answered it in an accessible and understandable way. Thank you.
