MCA

Dear B.Tech is better than BCA+MCA. So in my view, you should join B.tech. rather than BCA. For this you can choose top private college which has good placement record which totally depends on education system. In this sequence, I want to suggest you that you can choose Anand international college of Engineering, Jaipur. This college has following aspects:
(a) Implementation of modern educational concepts & associated internationally renowned faculty from IITs & abroad.(b) global exposure by signing MOUs with many renowned technical universities/institutions of USA, UK, RUSSIA & Thailand etc.(c) Flexibilities for choosing additional courses over RTU, Kota, Faculty Members, Class, Class timing & peers groups of learning.
(d) project based learning, digital classroom and high level learning level lab in all department.
if possible, before taking any decision, you may visit Anand International College of Engineering, Jaipur.
All the best for your bright future!!!
