You may have heard about HIKNOS questions.

So what are they?

There are certain verbal reasoning question types that other publishers, such as Letts, do not include in their papers.

These question types ARE on all IPS papers.  In fact, "HIKNOS" is an acronym and refers to IPS questions types H, I, K, N, O and S.

So be assured that all IPS papers/books include HIKNOS questions!
