In the Moralis Academy, we have 39 Courses (and more coming). As far as the time goes, each Course is approximately 10 hours long. However, with the Professional Plan, you get a Personal Study Counselor and Study Guide, to shorten the learning curve for you. This is done by directing you to specific courses in a specific sequence, according to your needs and goals.
On top of that, there are additional assessments, tests, quizzes and projects that need to be completed - therefore that needs to be taken into consideration as well.
You can watch courses at your own pace and as many times as you desire to.
All the courses are completely open to you (with the professional plan), from the moment you enroll!
