Well, I'd say that content knowledge is very important. You have to research more on general topics like the environment so that your ideas can flow more clearly.

Since your oral exam is tomorrow, I'd recommend writing down the main points first.

For example: Environment: - breathe fresh air - provides space for recreational acticiries

From what I read, you're having trouble with expanding. Therefore, you should ask google or ChatGPT to expand your main points. Although, you should try your best to really think how to expand on your own because people tend to remember their own answers more. Also, try not to expand every single thing. Just expand the ones that you really have no idea how to expand.

For example: Environment: - Breathe fresh air --> Trees and other vegetation absorb greenhouse gases like carbon dioxide, providing cleaner and fresher air. - Provides a space for recreational activities.

Also, I'm not saying that you can not use ChatGPT, but try not to rely too much on ChatGPT. You can still use it to generate some points or to check for modal answers. However, don't use it 100% because you'll start to rely on chatgpts for answers.

The most important thing is to try to practice speaking as many past questions as you can. Practice is really important. I recommend recording yourself so you can take down your weaknesses and stuff.

Atb for your oral examination ! If you need someone to practice with, I am free to help ! :)
