GCSEs - a survival guide needed please

[Copper]

Huge row today with DS about lack of revision going on in April holiday, which got so bad that I think he may stop any revision just to spite me.

He was supposed to go in to school for an extra revision session today at 9.30. Yesterday he said he wanted to go but today, even though he was up and dressed, point blank refused. I completely lost it - he has done this before on coursework catch-up sessions and had a really bad row with his father about that. (will fail those GCSEs as a result. This session was for a subject that he needs for his A level choices.

DS stormed off for about an hour, came back and shut himself in his room all day, in bed. Attempts to talk in the day made it all much much worse - ran through all the old favourites - you hate me, etc etc.
Went to bed at night still furious with me.

I handled it all very badly.

Any advice on getting large, recalcitrant, stressed-out but much-loved 15 yr old through the next few weeks would be much appreciated.

Sorry - seem to have started two threads by mistake - upload seemed to have stopped so I did it again.

If anyone wants to respond, maybe you could the other thread?
