Which CDAC course should I choose because I'm from electrical branch?
Some more information would be necessary to answer this question. For example, are you currently a student or an experienced professional looking to switch job?
Have you already taken any courses already?
If you have the interest into electrical circuits, you can join CDAC’s PG diploma courses in VLSI Design and Embedded Systems.
If you are interested in Programming or other IT fields, there is a wide range of courses under CDAC. Could you tell your specific interested elaborately?
