Need help with math or science? As a civil engineer, 31, I am happy to help you! Learn at your pace and with many examples to clarify the learning material. I have years of experience in teaching simple and complex material. The lessons run as follows. First of all, together we look for the student's biggest stumbling blocks. These can be related to the subject matter as well as to the study method. From there, I continue to work at the pace of the student and encourage them to ask as many questions as possible. I also give them tips and tricks, and improve their working methods where necessary. During the lesson I give many examples to make the subject matter more interesting and we solve exercises together. Once the student has mastered the exercises from the lesson, I give some more challenging exercises to also test on the deeper understanding of the subject matter. In this way I try to optimally prepare the student for his / her test or exam. However, learning should also be enjoyable. That is why I always strive for a good relationship with the student through a spontaneous and positive approach. I am also very patient. All this lowers the barrier to ask questions and improves the student's learning process. Are you interested? Do not hesitate to contact me! See you soon! Tim
