Dear Girish ,

Yes , you can do MCA regular course with M.sc distance learning course as UGC approves to do two degree courses simultaneously, well..  in case of distance learning , there is no restrictions about age but only the basic eligibility .. if you have passed bachelor degree in any relevant discipline that you want to opt in masters , then you can apply for M.sc any times after that . You can try for IGNOU also as distance learning institute , as the issued certificate from IGNOUO is valuable in India as well as abroad !

Hope this information helps !
