Courses cannot completely improve your skills in trading. I think learning trading is about persistence, no matter how much money you spend on learning, but without persistence and good emotions, you will fall. In my opinion, the course only teaches theory and maybe it is good for knowledge. But you must have  the guts to try it with your own hands.

You may be able to find free courses on major exchanges like Binance and others. You can create a demo account to try out the analyzes that you have learn on the course. After understanding it, you need to try it on a real account. Do it slowly, no need to rush. Here you need to train your emotions well. Maybe it's easy to write it down, but it's not easy to put it into practice. The point is that you have to have persistence to trade.
