Depends on the show TBH. Some shows will have "nursery classes"/ fun/ casual classes (only jumps and tunnels normally) for dogs that are not entered in any other class (that's at independent shows)
Sometimes they are called Helter Skelter classes- like patch said they tend to be a speedy flowing courses but great fun all the same, especially if you have a speedy dog that drives on
.
Because it varies from comp. to comp. some of these classes might have 6 weaves in it but never have contact equipment and the jump heights are always low

I would go for one of those classes; that's what I did with my collie boy for our first show- it's nice because there is no pressure- just go out there and have loads of fun, don't worry if you don't get a clear round, although I'm sure you will

Alternatively if you don't want to do a "fun" class you could enter a jumping class only but there is 99% chance they'll be weaves in the course.
Is Ollie jumping full height?

Hope that helps
