My name is Esteban Alejandro, I offer private distance classes in Chemistry, Physics and Mathematics. Among the services offered we have the resolution of practical work, regular scheduled individual classes. Part of my experience is complemented with the assistantship in the subjects Analytical Chemistry and Bromatology I, as well as in food industries V. I am in the last year of my degree in food science and technology at the National University of Lanús, Argentina. I have 5 years of experience. The methodology that I propose is based on simplicity, and economy of steps. This will allow you to quickly understand the contents, and leave you prepared to successfully pass your exams in those subjects that are more demanding. This allows you to save time, pass your exams. You will also be able to sustain yourself in the rhythm of learning that the subject demands with support classes scheduled as the calendar year extends!
