I think eligible students option is must have feature. Now I can add new user and enroll him to 3 semmester. Another reason is related to different CCNA programs. I have student who change academy and he was learning by discovery program, after I wanted to enroll him to 4 semester i couldn t do that because he must pass 2 and 3 semester by Exploration program. I didn t know that without on line help, on this way I can enroll him straigth to 4 semester.
