Holder of a cantonal maturity with biology-chemistry option, followed by a course in forensic sciences at the University of Lausanne (most science courses being provided by EPFL), I am available to give support courses in scientific branches, whether at compulsory school level or at secondary level (and even up to the last year of maturity). For me, support is effective if the student in question is motivated and wants long-term follow-up, because there is always a time of adaptation before obtaining results which always end up arriving. In all cases, support is important to increase understanding in the revised material and also to compensate for potential accumulated gaps so that it is useful for the rest of the course. Everything understood is understood for all its life! Please note that it is also possible to work in the center of Lausanne in a quiet library or café if this makes it easier to set up support courses. In any case, do not hesitate to contact me for any requests or for more details.
