I read with interest your article about the new IB tariff ("Tougher A-levels knock back Baccalaureate", March 13). Many of us who teach the IB have thought for a while that it was over-valued against A-level grades.
The new IBA-level tariff strengthens the case for IB. It was over-valued, but that over-valuing has been corrected. Yet three A* grades will be valued at 32 points and three As at 29. This means the current offer for, say, medicine of three A grades at A-level is worth less than the worldwide average score for the IB diploma. I will continue to advise my students that IB is the best option in the sixth form because it seems to be by far the best route for gaining entry to high-level courses at top universities.
