It is what happens when you cut it so fine.
Personally, I would have not taken the last 6, let the 18 months expire, do that last 6 to restart the clock and the knock off the previous 8 again. It would have saved a bit of money.
No choice lad, get to your books asap.
This is your best aftermath solution-
Get those 6 subject first and the last 8 thereafter.This would be the best sequence.
