All universities choose what the exam will be like for the 2nd specialty and the evaluation criteria themselves. This means that the exam for the 2nd specialty can also be an interview, and there will be more opportunities than the entrance exam.

For reference:

2nd specialty - the study of an applicant with higher education for obtaining another higher education. In this case, if the applicant passes the exam, they will study from the 2nd year on a paid-contract basis. That is, students admitted with the 2nd specialty study one year less than others.
