I have a history degree in modern history. Most of the topics I have studied at university can be applied to either the GCSE or A level curriculum. Additionally, I also lived in Germany for almost 20 years. I can speak the language almost perfectly and my written German is acceptable.

The format of my class would depend on the needs of the student. List what is difficult or not clear and this would be the basis of the class. The speed and topics on each class would depend on the student.
The class would be structured around the student. I can also recommend books available from your local library that could assist in your learning experience.
