Hello dear,

Since you are from Andra you cannot apply for home state quota in any of the amrita university campus. For general category non home state quota rank goes maximum till 6k . For CSE in Coimbatore if you have home state quota closes at 13-13500 whereas in amritapuri it closes at 16k . So something can be some only if you have state quota otherwise chances are less. 

Don't lose hope still there are chances and chances for other colleges too. Visit career360 site to know the best colleges available for you.

Ask if you have any query in comment section.
