It's 100 days until the Scottish referendum and for the first time ever in the UK, 16 and 17-year-olds are allowed to vote.
Nearly 100,000 under-18s have already registered to have their say on 18 September.
In the run-up to the referendum, BBC Scotland's Generation 2014 project is following 50 teenagers and three of them have been to Westminster as they grapple with whether to vote yes or no to independence.
Newsbeat's politics reporter Jim Taylor was with them.
