I revised using the SPMM mocks alone and I think quite a number of their questions turned up. I only had 1 month to prepare so I didn't have time to do mrcpsychmentor. Those who used mrcpsychmentor, did you find it useful? I only did each mock once or twice and focused on recurring questions and topics. If I'd done them properly 3 4 or 5 times, I think the exam would have been a breeze.
