Excellent study methodology. It's always good to review the classes you've seen in advance, especially if you do it over coffee. Being a student in a demanding field like engineering isn't easy, but we just need to apply good study methodologies. Best regards.
Thank you very much friend, yes coffee has always accompanied me in my studies and I have even taken a thermos of coffee to my classes to stay awake, as you say my field of study is extremely difficult and very demanding. Greetings!
