In present day Nigeria so many graduates are whereas Nigerians with skills are able to battle and face the present economic reality. I have seen regrets lament that they would have learnt a skill instead of wasting five years in the university.
As a parent would you rather send your wards to the university or you would prefer they learn a skill or will they learn a skill before going to the university?
Based on the question from the topic on the thread, I think op you already know the best answer to the question.
Actually if you would ask me personally, I would say that the both are good, but as a parent you should ensure to enroll your child/children to learn skills while they are still in secondary school because after those days it might be difficult for them to learn any skill of their choice.
However, my point is that the both are good and students should at least have 2 skills before going to the university because they can even use it to sustain themselves before their parents send money for them. At least with their skills they can afford to buy somethings for themselves.
