If you are good with numbers and calculations go for Btech or Bcomm. If you are good with science . go for Bpharm or Bsc

If u wanna work in foreign countries than it is a best option for u

I think you are talking about PG or ,m.tech. You have many choices in civil engineering higher studies. You can choose any one like structural engineering, Geotechnical engineering, earthquake engineering, transportation engineering, highway engineering, hydraulic engineering, earthquake engineering, water resource, environmental etc

If you are a diploma engineering student and want to take admission in B.Tech, than some colleges offer direct admission to second year B.Tech. This entry to second year is called latera entry

Colleges these days have entrance tests as an admission procedure. So you decide, which college do you wish to get in and then inquire about it's details.

first join any collage like Christ university, Bangalore
allahabad university
Gujarat university
or join Sam Higginbotom Institute Of Agriculture Technology and Sciences, SHIATS, allahabad, Uttar Pradesh or for distance education join IGNOU and when your Ba(honours) psychology programme completed then prepare for TISS to more study and jobs opportunities and In Ma you can chose Ma(counselling) psychology programme and when your two year programme complete then u can get degree.

Yes you can pursue BE in computer science

Since you have very less percentage in intermediate, it is very hard for you to get a seat in B.Tech . I suggest you to get a seat in a good college through management quota if you can afford a huge amount for the seat. All the best.
