What does each exam cover?

Since the GL2 exam has passed I'm hoping this is not too late. GL1 is the core things, like dating methods, earth structure and the more scientific geology. GL2 is the more practical side, with topics like rock deformation, drawing cross sections and identifying rocks and minerals using the tests taught. Then GL3 is the topics like volcanic hazards and earthquakes, landslides and engineering methods used to prevent or manage the effects of these disasters, as well as the engineering side of tunnels and bridges with regards to testing rock strength and factors like it.

Best of luck with the exams (Y)
