To go round a roundabout you need to position yourself in the correct lane and indicate correctly and in plenty of time too.
To go left: position yourself in the left hand lane (the outer lane) and indicate left.
To go ahead: position yourself in the left hand lane (the outer lane) and this time indicate left just after you pass the entrance to the left turning, then go ahead.
To go right: position yourself in the right lane (the inner lane) and indicate right.
You have to remember to cancel your signals when necessary, and if you end up getting lost don't worry go round the roundabout again and be more observant to which lane and turning you need to drive to. However it's not advisable to do a u-turn on a mini roundabout because this is dangerous and could confuse other drivers to where you are going. You need to give way to traffic that is coming on your right because they have right of way, just before pulling off make sure you observe the traffic until it's safe to go and again be careful of motorbikes.
