I suggest Sibling and First child should be given 10 points to each instead of 20 to siblings.  For girls 5% is reserved and there are many all girls schools in delhi. So for parents who have a first boy child and not an alumni will not get any advantage...so  overall they are at lost from all preference. Cannot see any major change in case of siblings and alumni as still they will get 25 points as per the new guidelines. Earlier also I think they use to get around 20/30 points.Please given suggestion on this.
