What other changes would you like to see?
The Americans have been showing us how to do this for decades.
A single exam covering all the subjects, with a large, published bank of sensible, relevant questions. Each exam individually created from the published question bank by a random selection of questions from each subject area.
The Exams would be administered online by any Flight Examiner who would have to be present to invigilate the Exam, and identify him/herself to the online system with a PIN. The results would be automatically recorded at the CAA. (The system now used by AMEs to administer and record the results of Medical Examinations could easily be adapted for this purpose.)
Candidates could be recommended for the Exam by their Instructor, also with an online PIN, and 6 attempts (They could be called 'Sittings') would be allowed.

Ps. Flight Examiners could also use the system to administer and record Flight Tests.
