Is bca not valuable like btech?
Value lies not in the things you aquire it lies in things you retain permanently.
B.Tech. is a four-year undergraduate program whereas BCA is a three-year undergraduate program. BCA makes you adept at the application level whereas BTech makes you proficient in the technical level.
Coming to value it totally depends on you .
The more you update your skills the more value you make for yourself so just keep learning.
Hope this helps you out
All the best
