₦airaland Forum

I'm doing a research about students' means of learning/studying in Nigerian higher institutions. I have listed three here:
1. Internet/ PDFs
2.Textbooks
3. Handouts
Which one do you prefer? Why do you prefer that one over the rest. If you use them all, how often do you use each one of them?
Please, I need a positive response from current and former students. Thank you.
