and bring it with your student ID and passport when taking test.
2. ask any of your classmates or relatives to go to your original univeristy's transcript office to get enough copies.
and ask them to help you sent out those transcripts directly to the law school that you are going to apply. Dont need going through LSAC because you are international student.
