I have few queries re upcoming MRCP1 exam

Hello helpful people, I have few queries re upcoming MRCP1 exam. Hope some experienced MRCP candidates would be able help with these confusions.

  1. Do questions from Passmedicine repeat in the actual exam?

  2. Past papers available in Pastest online Q bank: are they actual past papers? Do they repeat in the actual exam?

  3. Sample Qs in MRCP UK website: do they vary in each exam? Shall I practice it just before the exam?
