As the other posters have said, it depends on which university you plan to apply. I would suggest you investigate further, by contacting the respective institutions as the entry requirements to all courses change on a regular basis.
In most cases, I suspect you should prioritise your academic results so that you can at least be considered.
However, I would also recommend you consider volunteer work. In most career paths, there is a distinct difference between the common perception of the job and the day-to-day reality. As a teacher, I see many graduates leave the profession after 12 months or less, not because they aren't capable or passionate - but because they "didn't realise this is what it's like". (Eg: as a Maths teacher, less than 10% of my time at work is spent standing in front a class teaching maths). I strongly recommend anyone interested in teaching do some volunteer tutoring before you pay for a 4-year teaching degree.
Its the same with many other careers. Medicine, in particular, has similar problem with a lot of high performing students feeling social or family pressure into following the pathway due to the perceived prestige of the profession, or financial rewards, rather than because of the personal satisfaction, enjoyment and reward gained by doing the work. And if you don't like the day-to-day work (in any job), you won't be good at it, and you can risk mental health problems later in life.
