Human Rights Act question

hi i would appreciate if someone can help me on a HRA question. i am new to F4 and it is kind of hard to understand. This will be my first paper based exams so adjusting from cbe’s to paper based is alot because i dont really know how to start answering the questions. the question i need help with is:
In what ways has the Human Rights Act 1998 had an impact on case law and statute?
i would really appreciate all the help i can get!
