Are snap cracku mnocks a bit lengthy and difficult compared to actual?

Actually no, they're on the easier side. I think the actual test will be slightly more difficult then the mocks.

Being someone who is very familier with the paper and its pattern ....They are actually at par with the actual SNAP exam , the difficulty and all are all upto the point so + or - 4 to 5 marks atmost is what you can expect if the actual paper turns difficult or simple

snap is comparetively harder and lenghty than snap mocks .
