I worked as a science and chemistry teacher at an International Bilingual School in Lille, France, and I was in charge of teaching a customized Inquiry-Questions Science program based on inquiry approach and hands-on experiments to middle school students, and the IB chemistry program, 2025 edition, to grade 11 students. After having participated in training courses organized by IBICUS, I am now familiar with the new roadmap and the changes that have affected the chemistry exam papers. Having had two years of experience in the secondary teaching of Science, Chemistry and Physics (years 7, 8 & 9) of the British Cambridge curriculum in Cambridge accredited international schools in Tunis, as well as more than two years of experience in tutoring grades 11 and 12 students taking the International Baccalaureate (IB/DP) chemistry exam, I admit that I have been fortunate enough to gain a tremendous amount of skills to teach in a diverse cultural environment.
