Unfortunately, some educational web sites prevent people from some few countries to participate in their courses, just because of United States government sanctions. One of these web sites is www.coursera.org.
But good news is, there is other web sites which don’t behave like those web sites and they present their courses for everyone from any country. In fact they understand rules of sanctions, because sanctions are not relate to these online educational courses.
For example https://www.edx.org and https://class.stanford.edu/courses presenting their courses for everyone and you could continue your learning by them without worrying about unacceptable behaves from them just because of your country.
With wish of freedom for everyone.
