Do you supply spare microscope slides in case of breakages for Paper 3, Advanced Practical Skills exam?

We do not supply additional slides for the exams, it is standard practice for two students to share one slide during the examination. Candidates are assessed on their microscope skills, and they should be able to use the correct techniques to avoid breakages. This should include starting with the stage up high near the lens (look from the side to ensure the lens does not touch or go through the slide) then focus away, so the stage is moving down.
