'Nerve-racking' for 16 and 17-year-oldspublished at 15:31 British Summer Time 7 May 2021
Three pupils from Stanwell School, Penarth, cast votes for the first time and described the excitement of the process.
A-level politics student Davis, 17, from Penarth, said it was "nerve-racking" as his course has taught him it is about people giving the power to others and "putting their trust" in them.
He voted Liberal Democrat for the constituency and the Green Party on the regional list.
Amelia, 17, from Sully, said last week's debate television shows influenced her and she voted Labour constituency and Liberal Democrat regional.
Jed, 16, from Sully, said: "I voted Labour on both votes. I was looking for the party that helps the most people and they were who I believed would."
