Night as well !

Doing the IMC course in one week would be demanding, doing the Night Rating
as well.............and you would need to be lucky with the weather.
If this is your chosen course your options become limited to those
airfields which will be open at night (remember British Summer Time comes
in to effect at the end of March)
For the IMC, make sure you have studied for the written exam before you
start flying. However I would suggest you don't actually sit the exam until
you have started flying approaches. Just my opinion but, like the PPL exams,
you would find it easier once you have some practical experience
to help with Nav, decoding plates, etc
