Biology is just a boost, not a pre-requisite, for medicine. Though it'll help when it comes to concept understanding.
Physics, however, is where my interests lie in contrast to Biology (not medicine!)
This is why...
The remnants of a supernova may form a neutron star. However, if enough matter is left behind, it may contract under its own gravity to become extremely dense, with such a strong gravitational field that nothing can escape from it. This includes electromagnetic radiation such as light, so it is called a black hole.
Dark matter
Scientists have suggested that the matter we can see – stars, planets and galaxies – are only part of the mass of the universe. They have suggested that most of the mass is actually matter we cannot see, called dark matter.
The existence of dark matter would allow scientists to explain their theories. However, some scientists doubt whether it really exists. They have suggested that our laws of gravity need tweaking to work properly when very large objects and distances are involved.
That's why Scientists are still searching for this dark matter.
I'm not saying that this will be covered in H2 Physics syllabus though, H3 maybe? But there's still relevance to this in H2.
And when there's interest in a subject, there's this amazing thing in you that makes you grasp theoratical concepts fast.
But after all that has been said, my interests still lie with Biology after sample lectures at TJC.
Hence, possible subject combi would be BCME or KI & BCME (with Bio as H1)
May everyone consider very carefully about choosing their subjects for there is still ample time.
