Hi Sandra,
Personally, after my CBT I bought a 125cc bike and rode it around on L plates for a (long!) while and took a few lessons before tests. I would have preferred to get all of the training and test over and done with quicker than I did though. It was a matter of cost for me in the end, as I had put aside enough money for 4 days training for shortly after my CBT... and promptly went and spent that money on a guitar! Whoops...
A few people on this forum have said that they found that doing Direct Access as a week's course was good, with the test at the end of the week's training. But yes, it does depend on the person.
There is a lot to be said about getting a 125 and riding it on L plates for a bit until you get the hang of things, from my experience. It means you don't feel lost when you pass your test and are allowed to ride around on your own
