Like all algorithms it had bias built in - one of which was to inflate private school grades, making grades even worse of a measure of quality than normal.

What was particularly inexcusable though was the government response - the implications of the algorithm were available to the government weeks before the results, and the public backlash from Scotland having similar problems happened a day before.

Now you could argue that to avoid grade inflation as a while the government should have proceeded regardless, however wen the inevitable backlash occurred (predictable since July and known since the Scottish exam results earlier in the month) they turned round.

This u-turn came too late for many students to benefit yet wiped out all benefits of grade inflation prevention - literally the worst of both worlds.
