Can I ask what the difference is between Undergraduate and Novice please ?
Both seem to be for dogs that have not won three classes- or have I read it wrong ?

They are different qas to which classes you have won.  Novice is any classes other than puppy ones at Opene and Champ shows.

Thanks
can i ask- is undergraduate for those who havent won 3 classes at Champ shows ?

<UNDER-GRADUATE For dogs which have not won a Challenge Certificate or three or more First Prizes at Championship Shows (Minor Puppy, Special Minor Puppy, Puppy and Special Puppy classes excepted, whether restricted or not).>
