The step2ck exam is not only about knowing the subject matter but also applying it on a given time.Can any one share us experiences on how to save time during the exam?

I think the best way could be not to go through everything written on the question.You need to be focused on the most important part of the question, read the C/C and jump to the important part of the PE and lab results.
If you think that you need further information, then you may go back to the detail of the question.The UW simulating exams are quiet good guidance on keeping the pace at the big deal
