Not too easy. Not too difficult.
Longtin is a great professor at explaining the basics of Thermodynamics. You will be fascinated how he can use those amazing analogy to help you understand these terms in thermodynamics. Of course you have to devote some time into it. But trust me, it is rewarding.
I learned the First and second law of Thermodynamics. I understand how our world generate electricity and what is the basic idea behind our refrigeration systems and Car engines. I know how to calculate the efficiency of them if proper data is provided.

Advice for students:
You need to go to class. Longtin is giving reward to those students who go to class. For example, some questions that will definitely be on the final. And you have to study yourself. You can only remember those terms by practice. So do you homework.
