Hi guys, can you help me with one or both of the following questions, thank you very much.
1. Since 90s, education has become ........................
I am writing this for a report (essay), is the expression (Since 90s) correct or formal?
Is there another way to say it?
2. "When people realise the need to store their knowledge, thoughts and information permanently, along with the need to broadcast them on a large scale, they soon discover the limitation of Oral Education."
Here, the phrase "oral education". I don't mean the education that teaches you how to speak, I mean the education that uses oral as a medium. Is there a better phrase for this word? Thank you ver much.
