Actually, I cannot! especially when curriculum keep changing now and then to accommodate books of writers (authours) that have bribed their way through the educational board. Funny enough curriculum will change will no proper provision of materials for usage by teachers and students. Honestly, Nigeria greatness is tied to proper restructuring of our educational system.
However, being positive is the way to go/live. Because the few numbers today that are implementing what they learned might become a great one tomorrow. And you and you..... and yes me too could start by standing out and truly learn and put to work the knowledge acquired.
