Giving P6 and P7 in September'2018?

Hi guys,

I needed your opinion on whether it is good to give p6 and p7?

Considering-

– The exams are back to back
– P7 is a re-sit, got a 48 June sitting.
-P6 is huge and is it manageable with few hours to revise.

I am a full time student. About 38 days remaining. I’m yet to start the preparation.
Can Invest about 7 to 9 hours a day.

Need your opinion guys.

Thanks in advance
