You will do great, and so they are young. Just think you being older might have an advantage all that life experience.
Any hew diamond you know that you can do anything you put your mind too whether it be with a classroom of chimps, youngsters, those the same age or pensioners.
Remember you are also never alone here and at home you aint either. So just go for it :)
GOOD Luck
Lots of love and best wishes
