For me is not really good idea to learn driving then stop then go back learn driving again, dont leave gap in between of your driving lessons, as you have chance to forget what you learned, it willl only cost you more money and time!
I did 2hrs per week starting late May 2008 then passed my driving test Middle of Sept 2008 so I did in total of 31 hrs of driving lessons, I also spread the cost of my driving so it doesnt hurt in my pocket
Goodluck to you too!
