Before tackling actual IRSE Exam layouts I suggest starting off with the attached relatively simple layout as an introductory exercise.
The idea is to complete the grid on the other attachment- it is a bit of a mixture between a "Route Box" and a simple "Control Table".
The IRSE exam will actually provide the route boxes to define the use of the layout and expect rather more of the candidate for the Control Table, but this exercise should discover whether you can can read the layout symbols, decide which signals have which routes, comprehend the use of the layout for the moves specified on the layout description. Similarly it will find out if you understand the essence of interlocking and can work out where the overlaps end etc.
Complete it by Monday 1st June and post your answers.
