Section A of the Leaving Certificate chemistry paper has 3 experiment questions based on the mandatory experiments on the course. There are around 35 experiments in total. Some people find it difficult to remember these experiments from books and notes so we have put together a Leaving Cert chemistry playlist to help you learn them!
