Andrew Chen discussed about how to deal with schools warning. US schools usually give students second chance, the first for warning, the second for dismissal. When receiving warning letters, the students need to pay attention to their study and their GPA. After the warining notification, the students only have one chance to prove themselves. In most cases, universities would nofity their students by email. Most students are not used to check their email in time, which causes them in danger for dismissal.
Andrew Chen explained the differences between dismissal and expulsion. After getting dismissed, students can apply for readmission to the original school if they can revise their attitudes of study. However, for expulsion, students cannot be readmitted from their original schools, which is forever dismissed. Most students get dismissed by their US universities, so they still have change to go back again.
