No, you can't get admission. You have to first clear your exams. All the best.

First, you should clarify what type of computer course, but if you fail in 12th I don't think you will get admission in the college.

Yes, you are eligible for lateral entry as you are from vocational course background you will get admission straight into the second year. So, don't worry go for it.
Best of luck.
