Relax dear, they are only entry requirements.
Do the PPL
Can start the CPL ATPL GS immediate on issue of PPL license if sums and grasp of Queens English up to speed.
Need 185hrs TT to start CPL SKILLS TEST and passes in GS exams (9 or 13 depending on which route >> CPL or ATPL)
Can't get a night qualification until you have 100hrs after PPL passed (so if you take 90hrs you need another 100hrs after that so pushing back the date of your 170a test and the CPLH ST.
