Discourse is the most difficult mode of assessment in the beast tamer theoretical examination.
Instead of answering using a brush, one answered by speaking with his mouth.
When answering through writing, one is free to contemplate over the question for as long as they wish. Even if they were to write wrongly, they are able to change their answers. However, a discourse is not like that.
The examinees aren’t given thinking time or an opportunity to change their answers. The moment it starts, the examinee will have to answer all questions correctly. If he were to spout a single erroneous word, it would mean his failure.
This examination model is similar to the Pill Debate of the Apothecary Guild. It is specially prepared for master teachers so as to reduce the time required for the examination. At the same time, it assesses how well-versed one was in the knowledge of beast taming, as well as how fast one can access that knowledge.
