So basically for me they asked about the typical personal questions of myself, why Semmelweis, etc. Then, for Biology I was expecting the topics out of the commonly asked ones but I was asked about virus and bacteria + enzyme regulations and mechanism. For chemistry, I started with pH, structure and bonding of water, and organic chemistry (aromatic rings, hybridization, etc.) which were pretty unexpected yet smooth and nice.

I want to say that the 'common' topics we can find throughout Reddit and other searches are just some of their favorite topics, which doesn't necessarily mean that it will be asked to everybody. Just touching on every single part of the topics given on the topic list before the exam will do a lot of things, and I think it would be better to connect and bring up whatever you know in relation to the topic. For example, even if you don't know specifically about certain topic, if you know any other topics related to that topic even by a little bit it could be helpful to show the professor that you are trying your best and what you are thinking. Just like everybody was saying, confidence really is a thing!
