Leaing Online program is attended mostly by high school and college students from all over the world. Our students are selected based on their academic performance, writing skills, and interests in research. These are determined by an application process and a round of interview. However, due to the difference in students' class standing, students are divided into two groups, basic and advanced. This helps our professors can provide more tailored content to each group. Of course, there are high school students who are advanced enough in a research area to be in the college-level group.
