You can take your course anytime you wish. There is no specific time you must start—it’s entirely up to you, as long as it’s within the course access period, which is usually 1 year. All courses on DoviLearn are designed for self-paced learning.
However, for bootcamp courses that include live classes, or for courses that are purely live, you will need to join at the designated time. But don't worry—if you miss a session, you'll still have access to the recorded classes.
