This course was genuinely a great experience. It takes a topic that can feel complex at first and explains it in a way that is clear and easy to follow without losing depth. I really appreciated how it connects the software side with how battery systems actually operate in real energy markets, which made everything feel practical and relevant. The exercises were especially helpful because they allowed me to apply what I was learning instead of just watching or reading. Overall, it feels like a well thought out course that gives you both a strong foundation and a real understanding of how things work in practice. I would definitely recommend it to anyone interested in energy systems and software.
