,About the book
Education is a key for a countries development, but it becomes a hindrance when it is unequally
distributed. This big problem of disparity in Education system can be solved through technology.
Hence it’s high time we embrace technology in Education sooner than later.
Teachers will therefore use the book in their laptops to teach and even give students notes to read
online after revision.
The book is divided into three parts:
Part one – paper one
Part two – paper two
