After finishing secondary school, some students decide (to take) a gap year and go 2(travelling) I think it is one of the best decisions a young person canmake. My brother 3(went) around South America and the USA last year, and I hope (to go) to Australia after my exams. Some people are worried about travelling alone because they think it might (be) dangerous. But I think it's fine if you plan your trip carefully and you (do not take) risks. Of course, you can travel with a friend. My best friend and I (are planning) our trip at the moment. There is a lot of information about gap years on the Internet. But I think it's a good idea to talk to people who have already (done) their trip. You can find out such a lot.
