Its a great initiative to visit the campus at this stage. As an ISB alumnus, I know that ISB has strict rules on class participation (e.g. people not enrolled for the course cannot do class participation). Hence, you may refrain from doing that but ask your queries by interacting with the prof after the session is over.
You should definitely take the opportunity to discuss the life at ISB with the current class and get your queries answered. For more info, I will be happy to help too
