Software Engineering

Hello Richa Kumari,
After 12th, please go for national level engineering entrance exams like JEE, VITEEE, SRMJEE, BITSAT, etc. and opt for either computer science or IT engineering.

MCA is defacto the most accepted degree by Apps Development and Maintenance companies in India.

CSE would be a wider option for you though software is a part of computer science and will not be so vast. CS would be more suited if looking for thesis or research. Software engineering will be more suited for job opportunities.

The following minimum scores are required to be considered for admissions into the MS Software Engineering Program:
Quantitative + Verbal (GRE q+v) score = 294 or higherAnalytical Writing (GRE AWA) score = 3.0 or higher

Hello Anil,
Join M.Sc computer Science next year. Start preparation for entrance exam of college right now. Also with this, do some certification course in Java, C+, .Net, PHP, etc. Any of it will help you in finding a job.
If you don't want to do M.Sc than you can do MCA or M.Sc IT also. but I suggest you personally that go with computer Science.

You should opt for B.Tech in CSE if you want to become a software engineering.

For higher studies, you can go with GRE or CAT also. GRE is basically for students who want to pursue there higher studies abroad, specially in US. CAT is to get into Indian MBA colleges. Getting good marks in these exams can place you in one of the finest universities in India as well as abroad.

Universiti Teknologi Malaysia, Xiamen University Malaysia, Taylor's Univesity, Universiti Selangor (UNISEL), Universiti Teknikal Malaysia Melaka -UTeM are some good options. Please visit their websites and write to them for placement assistance details, they do have industrial tie-ups and provide good career support.
