This is true that every parent want to admit their children at good age so that he easily gain learning. and most of them are confuse that what will be that age so that they become intelligent and in this thinking they have face many difficulties..

In my opinion the best age to carry yuor child to school is 4. At this age let him free and do not take any tension even if he gain nothing. After one year then admit him officially in same year of KG, so it will easy for him now to gain learning..
