David Kohler

Hello, I'm David, 22 years old and grew up Germany and just finished my bachelor's degree in Biology in Constance. Recently I moved here for my master's in Toxicology at the State, which is taught in English. Accordingly, you can take lessons in Biology or Chemistry (secondary school level, in English) or just English and German as a language.

While I don't have any experience in teaching, my study mates told me that I should consider teaching as an alternative career, after I saved my mates multiple times from failing different exams the nights before. If you are a student at secondary school (15-18 years old) and want to improve your English, German or Biology, feel free to contact me. The first lesson is free, in order to get to know each other and also see if my lessons and atmosphere match your needs.


First of all: My philosophy is to not only help with your current topics, but also give a guide on how to study on your own and provide a blueprint for how to tackle different subjects and learning methods to build a good and effective learning routine. Trust me, after 3 years of my studies, I have tried about every methods there are out there, and I am sure that I can help unexperienced students with that, because the struggles in different subjects usually have their origin in not knowing how to study (because no one teaches you that unfortunately).

After getting to know each other after a quick chat, you will explain your current situation (experiences, struggles and your study goals). Afterwards I will explain the methods and pace fitting your current situation. Preferably, you can provide a short summary of your subjects and topics that you need help on, so we can discuss in detail how to design your individual lessons.
