Acharya is better for mechanical engineering. You can judge the colleges on the basis of infrastructure and teaching quality.

B.Tech degree is always considered better than a Diploma. I feel you should go for B.Tech in CSE. It has a great scope.

Hello,
It's very nice to hear from you that you are interested in doing your graduation in engineering in Dairy branch. It's great. But unfortunately for getting admission in any engineering college, a student has to appear some or the other entrance exam. Hence decide and prepare for these entrance exams if you want to achieve your dreams.
Best wishes to you.
