Hi,
Dont worry abt the most tricky questions AND questions which are not clearly stated (properly phrased) ... Consider the remaining questions and see how well you have answered. That grades you!
I am not saying that SCWCD questions are straight forward. But wanted to say that mock exam questions are sometimes out of the way, as they concentrate to bowl you out
Finally, be confident on your preparattion. If you feel your preparation is not worth it, postpone your exam! HFSJ is the best exam which grades you properly.
All the best!
