Ryanair training is superb, but as for sim checking, it is the only place I have encountered where I sense the objective is constantly trying to trip up the candidates (for example, rattling off RT instructions so fast, or so timed, that the co pilot gets overloaded or confused, and why must the Cat3 fault always be the nastiest possible AP disconnect during the minimums go around?). Generally no biggie for the Captain, but for the FO, a 4 grade can delay command considerably. Normally I would be sceptical about a post like samca's, but it does kind of ring true.
