NO....
1. some people are allergic to mammals.
2. there are lots of bacteria in a school area that are strong enough to effect your guinea pigs health.
3. most people at school are not used to handling small rodents such as guinea pigs.
4. most rodents are clever and they may escape + be never to be found again.
5. a student might get sick and you could be charged an amount of money to cure the students sickness if its serious.

Take them to a vet!
take it to the vets
About 3 months.
What if your Guinea Pig has just had a baby - what call a vet or what?
Take it to a vet! NOW!
in my experience, it takes about 2 monthes
a baby guinea pig is known as a Pup. (though never a puppy)
when my guinea pig had babies i held her and she was fine
it is sick? take it to the vet
One would be crying and throwing his or her guinea pig
you can't. unless you have a trained guinea pig that somehow can talk to the baby and say what you want to tell it.
