Network Critical Path Help

Hi is there any easy way to find critical path in network for multiple choice exam !!!!

Just find the longest path? I'm not aware of any trick/method to it that would be any more efficient and time-conservative. Following up each path from start to finish is always a safe bet, finding the time taken along each path and ultimately taking note of the longest path (being the critical path). Dummy activities can often be used for a critical path, so I find it's always a good start to look at paths involving one.
