Hello aspirant !!

The selection ratio is nearly 1:5 or 1:6 ,changes every time. Allen Alpha Achiever batch is one of the best batches for NEET coaching in terms of faculty and materials. But only physics and chemistry is being stressed upon with a thinking that the student is well with Biology . Keep this in mind before joining .

Also 556 is a good score , you can get good colleges through state quota , even a few through AIQ. Why taking a drop ? Anyways it's your call .

All the best.

Hope this helps.
