The training institution you mentioned should be self-taught. If it is, it is not false. But within two years, you can only get your diploma if you pass all the exams and all the subjects. It doesn't mean that a diploma will be issued after two years of study. So you have to ask them if they were trained by self-examination.

2 getting the undergraduate diploma quickly is a continuous reading at the junior college level. Your friend is right. It's just going to be harder. But you have to believe that there is no shortcut to learning.

If you take the self-study exam, you are free. You can choose to attend classes on weekends or full-time classes. So is the diploma.
