Some states let you retake it and give you a second chance m, if your country doesn't do that then you have higher chance to take more, every year you get to take one and it determines if you get credit or honors, you can also do community service to get you more points, that helps a lot too once you get to a higher grade you get more options and tests you can take for credits and honors, I wouldn't be that worried.:)
It might be tuitions or grants.
It’s hard to count on peoples easily with many other
Norms promote the aims of research. Ethical standards promote the values that are essential to collaborative work. Researchers can be held accountable to the public. It also builds public support for research. And many of the norms of research promote a variety of other important moral and social values, such as social responsibility, human rights, animal welfare, compliance with the law, and public health and safety.
Hope this helps!
Brainliest would be nice but you don’t have to! :)
