The Jepp into the Comms exams? No! Why would you want to do that?
You must take the Jepp into the Flight Planning exam. And you are allowed to take one chart (they'll tell you which) into Gen Nav, although they'll give you a (very bad) photo-copy of the relevant part of the chart if you don't want to use your own. But I can't see what use it would be in the Comms exams!
