I'm (19F) in my first year of college and even before this I've never raised a hand (or even my voice) in any class I've attended online. I'm always scared to be wrong or people judging me. But yesterday, our professor mentioned that we will be graded in our internal assessments based on our interactive skills and that's when I realised that I'm doomed. 

Anyhow, today, for the first time in my life I raised my hand in class and although (thankfully?) the teacher didn't notice me it was a big step for me.

Can ya'll suggest ways I can overcome my anxiety and speak up confidently in class? It seems to be so easy for the others in my class but I get all worked up and sweaty and shit. I desperately need to maintain good grades (\*cries in asian tiger parenting\*).
