Let's refresh the two ways in which you can tackle this decision:

When selecting subjects, there are a series of steps you can take to help you determine which are your right subject choices:
Decision #1: What to do about mathematics?
(Aspects to consider: passion, aptitude, type and level of math)
Recommendations: Try to take the highest math within your ability and the type of math course that underpins your other course selections.
University and Course - What type and level of math is needed for your course/s of interest at specific universities? The highest ranked and most competitive universities tend to request certain type and levels of mathematics (and certain grades) - especially for courses such as engineering, finances or economics. Research this answer.
Decision #2: What to do about science?
(Aspects to consider: passion, aptitude, type and level, matching math course selection)
Recommendation:
If you might study science at university, it is better to take a least one of the three natural sciences below.
* Physics – Math AA (take both HL)
* Chemistry –Math AA (HL or SL), Math AI HL
* Biology – language-based (content course - least amount of math): Math AA (HL or SL), Math AI HL
Other specialized sciences should be taken as a second science.
Computer Science, Design Technology and Environmental Sciences and Societies – not always recognised as a science at university. Students that are interested in art and design or that have little interest in science might consider this option.
University and Course - What type and level of science is needed for your course/s of interest at specific universities? The highest ranked and most competitive universities tend to request higher level subjects (and possibly more than one natural science subject). Germany requires one natural science, and either a langauge, a natural science or Math needs to be HL (for any course). Research this answer.
Decisions #1 + # 2 creates a framework for the remaining decisions.
How many courses have been determined already? Lots of courses still to decide or only a couple of choices left?
Decision #3: Besides languages, have all my possible university admission requirements been addressed? If not, which course/s should I take?
University and Course - The subjects and levels in groups 3 and 6 that are needed vary for specific courses and specific universities. Research this answer.
Decision #4: If decision #3 doesn't apply to me, which course/s do I really want to take?
Recommendation: Consider taking a course that gives you high satisfaction! Look for balance within your course load ( heavy vs light, well-rounded profile).
Decision #5: Which Group One Language course and level should I take?
University and Course - What level of English is needed for your course/s of interest at specific universities? English HL may look favourable in Liberal Arts/Social Sciences degrees (especially for law, international relations, communication and journalism). Research this answer.
Decision #6: Which Group Two Language course and levels should I take?
Country, University and Course - What type and level of an additional language is required?
Research this answer.
