THE STUDY HUB
This blog was put together to help student currently in the computer science department of the Koforidua Technical University (ktu) to help have access to Past Question of each course of study in the Department,Solutions to each, PDF's on related course of study. Also this HUB is going to serve as a unit where student of the department can put questions and ideas on their mind to help increase academic performance .
