How can I get better at being confident in my answers?

I'm not sure if you're a high school or college student, so I'll give you some information as "both". I'm not a therapist but I think you should take an honest look at why you're embarassed about not knowing the answer. It seems to be that the focus is on "how you look" in front of others versus making sure you learn the material. I know that peers can be pretty harsh, but it's temporary. Nobody remembers that stuff years later. If you get it wrong, I'm pretty sure nobody will remember it by the time you leave class. Chat with your school counselor/or counseling center if you're college. They'll be a good sounding board for whatever anxiety you're experiencing, they know the teacher, etc.

Take control through practice! Toastmasters International, a public speaking organization, uses this practice/method to improve on impromtu speaking, it's called "table topics": Google a list of random questions that are maybe goofy, or philosophical, maybe common interview questions, etc. Don't read them!

Have a friend ask you one and give yourself 1-2 minutes to answer it. I'd do at least 5-10 of them every few days, mix it up. You'll get comfortable not knowing the answer and still having to talk anyways. But, in a supportive environment, with your friend. You can use a bigger audience if you like. Then, when you DO know the answer it will seem easier to talk in front of others.

Also, the Career Center at universities often has "mock interviews", they'll help you get used to interviewing and formulating eloquent answers. It compliments your communication in both your coursework and for your career prep.
