enroll in kindergarten class

[kohyoongliat]

1. I've enrolled my son in a kindergarten class.

Is the above sentence correct?

Is 'class' redundant?

2. I've enrolled my son in an art class.

Is the above sentence correct?

Thank you very much.

All the best.

1 It's OK, but you could easily get rid of 'class'.
2 Yes
