Feedback comes in all kinds of ways - written, spoken, summative, formative. In EAS we use feedback to help you improve your thinking about the subject, your ability with texts and ideas, and your performance in assessment. You should be constantly learning and seeking ways to augment and improve how you study, how you read, how you discuss, and how you write.
You will be receiving your essays back in class from now on. Please do seek out your seminar leaders in their office hours to discuss written feedback. Remember to use your feedback to improve your work - be it written, in seminar, or in the library - in the future.
