Rule 2:   

Don't skip assignments

Why? Because every assignment in this course prepares you for the next step on your learning journey. Those activities that you are allowed to skip will be marked as optional.

​

        Rule 3:   

Work on the course at least 5 days a week

Why? Because it will be easier for you to remember what you have learned before. Although the human brain prefers to work hard only for short periods at a time, it doesn't like to take long breaks. It's simple: you are learning new skills, but if you don't use them, you'll lose them. So, even if you simply log on every day to review an activity you have already done, it's better than doing nothing.
