From next year, A-levels are to be made harder, with tougher questions and fewer units, and a new A* grade. This is because the number of applicants with straight As has almost doubled in the past decade. But those re-applying may be worried that this will make their present grades worth less. They fear an A will become the new B. But it will take time for the A* to win acceptance. Only a few universities like Cambridge will be including it in their offers next year.
