See in regular schooling also, there are compulsory two papers, one is of English and another is of the other Indian Languages such as Hindi, Bengali, Marathi, Urdu etc along with the other combination subjects such as Physics, Chemistry, Biology, Mathematics, Psychology, etc. So if you do so, then its not a problem and its completely fine to do so. If you have wishes to go for the courses in Arts then also you will get a opening through such combination. So don't worry about any problem regarding this.
