I think any change is, to be on the safe side, announced by FPSC provisionally over 10 months prior so that candidates can prepare without a tense mind. Right now, hundreds and thousands of BA/BCOM candidates who have 14 years of education have finished almost half of their preparation, so it is best to defer this issue to next year or years to prevent any uproar against FPSC amongst those candidates by the end of this year.
