I have not taken either of these courses, but I have some advice that may help you. First, it is important to consider which subjects you are passionate about and enjoy studying. A strong academic track record is important, but a passion for the subject matter is equally important. If you are passionate about computer science, then option 1 is likely the best choice for you. However, if you have a strong interest in economics, then option 2 may be the better choice.
It is also important to consider the universities you are applying to and what they are looking for in their applicants. Some universities may prefer applicants with a background in computer science, while others may be more interested in applicants with a background in economics. It is important to research the admissions requirements of each university you are applying to and choose the A-level courses that will best prepare you for the application process.
Good luck with your decision!
