Dear student,
Yes, you can take admission in 2nd year of another college if you have already done b. Tech 1st year from some college. This is known as lateral entry. Some colleges conduct examinations for lateral entry while some take admission on merit basis. In admission by lateral entry students have an advantage of not wasting a year and transferring from one college to another. But not all colleges may offer this facility, so you need to do some research on this topic.
