# New Interactive Problems in May 2024

See which topics had new problems added in May 2024, and use the links to check the new problems out for yourself.

It's that time of the month when I get to share an update on the list of topics that have had new interactive problems added in the previous month - in this case May. The update is split into changes published in our Australian textbooks and our US textbooks.

As always, if there's a chapter or topic that you think is in need of some new problems - because it's missing something, or just needs a greater range of questions - do let us know by sending a message to our support team via the chat icon in the Mathspace app.
