UCAT free resources

Hey guys, I’m planning on sitting the UCAT this year, and I’ve been hearing multiple resources people use such as medify, medentry, and the UCAT’s question banks + practice tests.

I’m asking if it’s okay to just rely on the UCAT’s official website’s question banks and practice tests as study for the UCAT, and if it’s enough, if I do as many of them as I possibly can starting from today.

I can’t really afford the medify and medentry programs at the moment, so has anybody only used the official free resources as their only way of studying?

Thank you :)
