Jainism does not have “exams” in the usual sense.

If you meant main principles, Jainism is commonly explained through:

• 5 Mahavratas for monks and nuns
• 5 Anuvratas for lay followers
• 3 Ratnatraya: Right Faith, Right Knowledge, Right Conduct
• 6 essential duties (Āvaśyakas) in many Jain traditions

If you meant something else by “exam,” then in Jain terms there is no fixed number of exams.
