And, by the way, if you can commit just 30 minutes a day to reading the LotG, you can read from cover to cover every week or two. Imagine that. You'd have it easily memorized if you read the LotG 26 times a year. Hey, let's give you Christmas week off and have you read it 25 times a year. Still very good.
To answer your question, though, I can't speak for the UK, but I can say that in Canada, we have made a move away from standard, multiple choice tests and gone to video analysis questions. It's still multiple choice, but the test taker is presented a video clip of an incident, and given four choices of decision. It is up to him or her to select the most correct response.
Edit: I've just done the math and, assuming you read at the average adult speed (which is 238 words per minute), and you opted to read for 30 minutes per day Monday-Friday, you would read the entire Laws of the Game from Law 1 to the end in a week. That's 52 potential readings of each new variation. Imagine how much easier it would be to remember the law changes when you've memorized the exact wording of each law. Amazing! Just 30 minutes every weekday.
