Exam file created by Teach2000, a memory trainer and student assessment application; saves an exam in an encrypted format and contains questions for students to answer; used for distributing electronic tests to students.

Teach2000 tests can only be taken by entering a student password specified by the teacher. When the student is finished with the test, the results are saved into a .T2KS file, which can be viewed by the teacher for grading. NOTE: T2KT files can only be decrypted with the password used for encrypting the file. Therefore, this helps prevent unauthorized access to the test.
