I would suggest you to select Mass Com. This subject does not need any technical expertise and its concepts are easy to grasp. Furthermore, in paper 2, most of the question are very generic in nature and can be attempted with very basic knowledge. On the other hand, for Pol Sc you must have strong grip over theoratical portion. Moreover, in paper two you need to study world constitutions which are to be studied properly to answer questions analytically. Nevertheless, both subjects are very interesting and with smart study one can easily fetch 130 in exam.
