Hello. Unfortunately it is not possible to discover your experiences and progress in the course you have taken and it is not possible to present the reasons that would lead you to recommend this course to other students. You haven't even said the course you're referring to. This makes it impossible for your question to be answered. However, I'll provide five sentences below that you can use as a template to write your own sentences, based on your opinion of the course. Hope this helps you.
The course was very influential in my academic life, as it stimulated my knowledge, extended my information and promoted new knowledge that will be very important for my life. In addition, the course promoted very good social interaction, allowing me to make very beneficial friendships and meet new people with similar interests to mine. The course also gave me the opportunity to express myself and get my thoughts and opinions out, without fear of judgment. This freedom of opinion and argument made the classes very participative and fruitful and this is the biggest reason why I recommend this course to new students.
