Dear Student,

Yes .. You are eligible to do BCA from IGNOU while pursuing BBA from another college , but as you know , both of these course under bachelors degree .. so you may feel little pressure during pursuing simultaneously these two subjects .Because, BCA course includes some practical works also .. for that , you have to put some extra effort.. and may be you have to attend the practical class at IGNOU during weekends  . So, if you think that you can manage both of these course with your time management skills.. then, you may opt for BCA (as max duration for BCA is 6 years in IGNOU)

Otherwise , you can go for some certification courses available in IGNOU with your preferred domain.

Go to the official website of IGNOU for more details !

Hope this helps !
