For the benefit of those people wondering about how challenging IST can be, my take is that if you have passed the assessments and got to interview then you already have the capabilities required to pass IST.
The figure I was told by an OM is that it costs Network Rail around £60,000 each to put every candidate through the course, so they’re not going to select people they weren’t sure would pass.
That said, people do fail. Me being one of them. People don’t really admit it on here either, but I failed my final exam falling just short of getting a talk up, and as such I had to rejoin another course from Week 7, and subsequently went on to pass very comfortably. Having been in my box and meeting other signallers there are quite a lot that fell short and went on to pass too.
There was one person on my course that had failed previously who came back and passed. When I joined the other group there was one in that group who had failed previously and had to come back.
Make vital use of the sim group sessions, go through rules and quizzes together etc over evening meal. Take time for yourself too, that’s important. Have your cut off point.
For flash card revision I used the StudySmarter app, and basically put every question from the ‘quizzes‘ in there. If I’d done that from Week 1, I’d have passed first time I’m sure.
