Seems a bit out of order, find another more accomadating school Where I done my test (not das but they had the same approach), they put you on a bike for about 30 mins when you were booking and assessed what level you were at, then gave you the number of days they would need to get you to pass. Basically if you then failed they gave you more lessons for free, so cost a tad more, but meant they were commited to getting you through the test. Research into different schools seems like a good idea at this point, good luck, dont let it put you off!
