Sorry but I reckon your stuffed to be honest. Please before you retake your test learn to read them big circular signs at roadworks that say 50.
This is going be a very expensive lesson for you, the cost of the retest,the fines for the speeding offences, wont be small fines as youve already attended an awareness course, so you will be seen as a habitual offender.Then the real biggy, insurance, when you eventually get your licence back expect to be absolutely hammered.
Good luck aswell trying to find a driving job, most companies will not entertain you with that sort of driving record.
