I'm a student in the UK, and I have a computer science lesson every two weeks. Most people would think computer science is my favourite subject, as I started coding from a very young age, but the computing teacher cannot teach it properly.
Secondly, we had a test recently, and I answered all the questions correctly (to the best of my knowledge, and checked after), yet she marked many questions wrong, for example, one question was “Why may someone not be able to access the sites on the internet (Give 3 reasons)”, and 2 of mine were “Legal Restrictions (eg, article 13)” and “ISP may be blocking/slowing down the website (Due to the removal of net neutrality)”, and she marked both answers wrong. She also gives incorrect answers marks.
She also teaches things which are incorrect, like “This spam email is a spam email because it recommends using Firefox, which is an insecure browser”, and when I say it is not, she says it is because she doesn't like using it.
Is there anything I can do about this?
