percentage to get an A in eng??

Grade thresholds vary each year with the results but they are NOT for languages. For languages such as URDU and ENGLISH an A grade is at 80% and A* is at 90 %. Percentile is not applied to languages.

Nitrogen oxide and Phosphorus oxides are acidic because all non metal oxides are acidic. Aluminium oxide is amphoteric because it has properties of both acids and bases........( reacts with both acids and bases )
