A clever contraption designed specifically for GCSE students, this timer boasts an impressive 35 settings that allow them to visualize the remaining number of classes needed to finish their practical work. With each passing class, the indicator shifts down the list, providing a clear visual representation of the student's progress. To facilitate smooth operation, the device requires a 6mm bolt, washers, and nuts for the center mechanism, ensuring it turns with ease.
