Welcome note

Welcome to the 5070 – G.C.E O’ Levels Chemistry course. I love to teach & I wish education could reach students beyond the barriers & constraints of money & travel. So here is an endeavour to fulfill a small portion of my dream & passion.

The course has been covered in the following 17 Chapters which have been further distributed into comprehensive lectures.

The course content is comprehensive and concise in accordance with the 5070 syllabus. The material is good for students new to chemistry as well as those who want to revise it.
