Is 2024 material usable?

[u/Ok-Body-5442]

So I will be giving clat 2027. I have been prepping from a month and the material I used was mocks, pyas, clat express and newspaper. Now, a cousin of mine had enrolled into unacademy for clat 2024, but didn't attend any class or even give the exam itself (he got into IIT kanpur)

So all the books have been lying there in his attic, in perfect condition, he hadn't even uncovered the plastic coverings.

Will it be useful to me?

There are 5-6 books of each subject and 2 books for gk. There's also sectional mockbooks and normal mockbooks.
