Mine was Reproduction...
The Secondary School I finished from was something else....
It happened to be a Military School (Command Secondary School Kaduna)..
Where Biology was taught by different species of beings...
Only one teacher thought me as it should be taught... Late Mrs Lawal..
You can imagine the set of student during my era at that school...
Even though some are officers, Doctors, I.T expert, Architects and so on now.....
But we were all nuisance then...
Talking about the styles of intimacy to perform to have a boy or a girl, what style did the teacher performed to have his desired gender,
What too much adrenaline hormone causes, how safe intimacy is ideal, female reproductive part ( nick named it C.litoris )...
It was fun... CSSKD and other school surely experienced this even better than I think...
Give your BIOLOGY EXPERIENCE...

Reproduction . Used to b very attentive wen it came to dt

I also loved reproduction, but usually disappointed when practicals are not carried out

Nothing beats the topic "Reproduction" in biology
When I got my Essential Biology textbook in ss1, i went through all d pages in search for Reproduction,only to realise its an Ss3 topic.... Was so disappointed.....Waiting till Ss3 seem eternity but finally, it did came and luckily it was a friendly female teacher dat taught us.....Oboy see as class craze... At a point, d principal even had to come to check wat was going on....When he came, he saw a teacher and the topic "The female genital of a mammal" boldly written on d blackboard....He just smiled and left.
#Baddest boys be shouting "ride on Ma" from d back seats ....lol
