The central pool quota means basically those seats which have been obtained by the respective state governments or certain colleges through voluntary contributions such as the union territories or certain states which doesn't have any medical or dental institutions of their own.

The CW quota seats are basically for the deceased in the army force and the guidelines have been approved by academic council.

The order of priorities are as follows

1.Widows/wards of defence personnel killed in action

2.wards of serving personnel and ex -army men disabled in action . This also includes para military forces.

Hope it helps
