The EASA regs state that the requirements for licence issue must be met BEFORE the Skill Test can be taken - or at least, that is how they are being interpreted at Gatwick.
I would imagine that many instructors and examiners will interpret the requirements differently but you will run the risk of having a licence application returned from LSD FCL, should it land on the desk of one of the more 'officious' officers who goes through the paperwork and log book with a fine toothcomb.
Unfortunately, it is a lottery - some are more understanding and lenient than others and whilst this should never be the case with a regulator, it IS the case at Gatwick.
