Refresher course in driving

Today, had a feel on how is it driving from my house to school using the new car that my brother bought last week. I have not been driving since 3 years ago when I passed my driving test. So, this time I do hope to gain more confidence in my driving. I think driving on the road is fine but I am just not confident about my reverse parking especially at the multi-storey carpark at my house area. In future, until I am more confident to drive on my own, I will drive to school then my brother will drive from there to work.
