Some teachers tell me that not every student can achieve 5A*-C in EN&MA.
Try this experiment.
Think about any mainstream student you know currently in Year 9 or lower who you believe CANNOT achieve 5A*-C inc EN&MA.
Now imagine I give you £1m to spend on that student.
Imagine also that I promise you another £1m to keep for yourself if that student achieves 5A*-C inc EN&MA.
Do you think you could get them to achieve it?
The issue is not whether every student can achieve 5A*-C inc EN&MA but whether they can within the resources that are available.
It makes you think, doesn't it?
