Marc has "filled in the gaps" in IB Chemistry and Math for my daughter who is a high school senior. His explanations are clear and concise and she enjoys working with him. I'm glad someone so bright and skilled at teaching has been available to us.
After his first session, my son stated, "It was like he turned on my physics switch, and he made it fun too!"
Ludger is a great tutor. He has a very relaxed and informative style which makes learning a new language a joy. Rather than parrot reading from text books Ludger finds different ways of making the language 'stick' in your head. Simple German songs and games make you think about how the language is used in day to day activities and you are surprised how soon you are asking for things and structuring sentences.
