If you go by the photo of the candidate on an admit card issued by a university in Uttar Pradesh, Amitabh Bachchan is doing Bachelor of Education.  Yes, B.Ed.  

Thanks to Dr. Ram Manohar Lohia Avadh University, the Bollywood Megastar's photo is on the admit card of a student named Amit Dwivedi.  The shocked student told a news agency thus, "I have filled the second year examination form correctly with my picture but after I received the admit card, it had a picture of Bachchan. I have been allowed to give my examination after submitting additional documents.  However, now I am worried about my mark sheet which might also have Bachchan's picture."

There is a likelihood of an error happening from the student's end.  For example, wrong uploading of the pic by the employee of the internet cafe from where he filled up the examination might have resulted in the gaffe.  Most of the processes in several universities in India are automated nowadays.  The staff issuing the card wouldn't have scrutinized the photos one by one.
