I graduated in 2018 with a Bachelor of Science degree in Psychology from Dalubhasaan ng Lungsod ng San Pablo. I tutored students in classes and out of classes. I use a variety of strategies to tutor students that include: lecture, discussions about the subject matter, problem solving examples using the principles of the subject matter being discussed in class , homework assignments that are directed towards reinforcing what we learn in class , and detailed practice problems help students to master a concept. I also do thorough research on Internet resources or textbooks so that I know what students need to learn in order to master what is being taught in class .
