If the application has not yet been submitted, grades can be added to the application until 31 January. Once you have submitted your application, it is not possible to add new or revised grades. If, for instance, you do not meet the mathematics requirement, you can still prove your proficiency in mathematics by taking the IBA mathematics exam to compensate for a lower mathematics grade.
