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.
