I've got the "Five Adventures at the Famous School" Box Set but I don't think it has the correct books in it. Could anyone tell me what titles should be in the box? Thanks!

There is more than one box set - I can identify at least three and there may be more.
In each case the titles seem to be completely random and unconnected with each other!

Cover picture: Camp (and ?Wrong)
Contains: Camp, Three, Wrong, Eustacia and Excitements

Cover picture:n/k
Contains: And Jo, Princess, Island, Problem and Coming of Age

Cover picture: School at and Exploits
Contains: School At, Exploits, Wrong, Wins the Trick and Leader

Thank you. At present I have Princess, Island, And Jo. Problem and Jo Returns - so almost matching set 2. The cover pictures, however, are Camp and, I also think, Wrong. And the writing on the spines is in at least 3 different styles, although the books are all of the same era!

ABE has a box set

The Chalet School Box Set Five Adventures at the Famous School

The coming of age of the Chalet School, The Chalet School and Jo, The Princess of the Chalet School, A Problem for the Chalet School, The Chalet School and the Island

Picture on one side- is the front covers of all five, and other side is The Chalet School. If link works you can see all the pictures -

Thanks Ivohenry - I didn't think to look there! The first one looks exactly the same except for one title different so I will try to swap that title out with the correct one.
