When you're beat by a snake in the day time you'll always want to be afraid of ropes at night. This is an African proverb. Am a victim of what you've just explained about, so I'll continue to do my best to push him and my other children to do well in the subject. My teachers are in mass but in my country must unqualified personnels lobby their way into the teaching field. Most of them are qualified on paper but in practical sense they're no where to be found. Thanks for keeping faith with my post and your comments are words of encouragement. Thanks once again.
