i`m surprised your school did not sort this before your test. i remember sitting down with the CFI over a cup of tea, and him going through my training records and log book to ensure everything was done before the test.
we found i was about 0.25 hrs short on stall/spin awareness, and 1 hour solo. did this a week before the test, so that when i passed, could send of the forms to CAA to get the brown folder.
perhaps you should speak to them and negotiate a discount on the extra time needed.
well done on the pass, and safe flying.
