Cool. I'm glad you found this. Please go through all the former posts when you have time.

Actually, since you're a grad student, this series might be quite helpful for you. Most of the vocabulary presented in these posts is ADVANCED-level vocab. I originally compiled this material for my advanced level ESL students. Some of the words might be too high-level for beginner students.

Best of luck as you learn more. And Full Steem Ahead!
