You don't have to worry even if you miss a session. If you miss any session, then you can always ask your workshop manager to help you move your classes to a different session before the workshop begins, and it will not even cost you any extra charges. They will reschedule your session at another time when you will be comfortable with it. But in case you change the batch more than once then you will have to pay an extra 10% fee of the AWS course cost for every change. Also, all your progress will be lost and reset if you change the batch.The online instructor led solution architect courses offered by KnowledgeHut provides such flexibility for you to enhance your career trajectory and obtain your perfect role.
