I got my provisional around Dec 2012, took my theory test in Spring and then too around 10-12 hours of lessons. My instructor booked a cancellation for me when I was ready (I had about a week or two notice) in July.
I strongly recommend taking lessons around the centre where you'll take your test. You'll be familiar with the roads and your instructor can hopefully lead you through some of the test routes. This might not be a big deal if you're comfortable with the area, but its not a bad idea anyway.
You can take the tests as soon as you've got your provisional, even before you've been here a year. Factor in having to take the tests more than once. Most people don't pass the first times. It'd suck to have your 1 year run up, but not have your licence yet.
Best of luck. A lot of us have been there, so we know it's not all smooth sailing, but you'll get there.
