Permission to study additional course

HI,

I am a CA Final student currently pursuing my article ship (1 year completed). I am also doing Company secretary course, which I completed happily, but as u all must b aware that C.S.course too requires internship of 15 months, which is pending from my side as I m currently busy wid my CA articleship.So, I have finished all the theoretical aspect of (completed up to CS Final all groups) but internship pending which I intend to do after completing CA. I had taken permission in Form No. 112 for pursuing CS. Now since I hv finished that course, I want to do another course.

So, an anyone tell me whether I can take up another course( I have a doubt as technically, I have not finished CS.&  the student is allowed to take one additional course at a time). Also, if yes, what is the procedure for the same?  

Thanks in advance.
