The Seminar
Our seminars always focus on presentation skills: instead of requiring a written paper, we ask you to develop a captivating and authentic presentation. To prepare you for this, we will spend the first few weeks exploring how to give a good and engaging presentation. Through analyzing various talks, we will discover together what makes a great presentation, and later work on your presentation techniques through practical exercises. Each seminar presentation will be delivered in front of the entire group and followed by an in-depth discussion. This seminar offers you one of the last opportunities before entering the professional world to receive honest feedback on your presentation style and performance. Take advantage of it! If you're interested in learning how to give a convincing presentation and are open to honest feedback, this seminar is the right place for you.
