The principal feature of this course is the categorizing of particles by function. According to this method, it should be clearer why certain particles are used in certain situations. Instead of studying similar particles independently and without reference to one another, students can now see particles with similar functions arranged together so that they can be easily compared. The quizzes are also a main feature. One or more quizzes are placed at the end of each group of particles, so that students can immediately check and reinforce their understanding after finishing a particle group.
