It is important to learn and train your skills at communicating orally about a topic in an academic context. This will be useful for exams and when making presentations or contributing to discussions in class.
An oral presentation entails working in-depth with the academic material and you get to practice communicating orally - something you can use in many different contexts, even outside your degree programme.
Many students get nervous when they are to make a presentation – whether in class or for an exam. It is quite natural to get nervous about oral presentations, but there are different degrees of nervousness. Getting to know yourself and your nerves enables you to work actively to control your nervousness and avoid bad experiences in the future.
