Committed to PEOPLE'S RIGHT TO KNOW Vol. 5 Num 562 Sun. December 25, 2005       Letters to Editor IB System Nayeem Islam, Class-9, The Aga Khan School, Uttara, Dhaka Till date the English medium schools of our country have followed the British O and A level systems of education but now some of them like the Aga Khan School are switching to the IB system. One part about this is that it keeps science subjects like Physics, Chemistry and Biology combined till class 9 whereas O level separates the three at around class 7. This means students no longer have the depth of knowledge on each of the three subjects because integrated science is just an outline of the three subjects. This I believe will greatly disadvantage students in grade 9 when they will take science subjects as they will not have a solid concept of the subjects. Thus, schools shifting to IB system must ponder about this before the problem gets severe.
