Not all modules will be available to you as soon as you enroll within the Academy. At first, you will be able to complete only the lessons within the first module. After 7 days you will then gain access to the next module, continuing all the way up to module 4. Once a module is open, you will have access to all its lessons which can be completed in any order you wish. It’s important you don’t skip any lessons if you wish to get certified. Questions in the exam will refer to all lessons in the Academy.
