Therefore, the practical carries the highest marks. A student should not to take his or her chemistry practical for granted. There is a high rate of scoring a good mark in the practical is high. As we move further I would be giving you tips on each part of chemistry.

However, to get an A1 in chemistry requires you to be able to read and understand chemistry concept. So many students find it challenging to grasp the concept of any topic in chemistry, as a result of this, they are not able to tackle waec chemistry questions.
