General advice for A-level students wanting to pursue quantum physics I am a student and I will hopefully start preparation for my A-level examinations this June. Unlike most students in Bangladesh, I plan to build my future based on Quantum Physics and thus have not received sufficient advise on what to do.  

Edexcel offers many subjects for A-levels but I am unsure which ones do I need.
 So far I am sure that I need:


Chemistry (All 5 units)
Physics (All 5 units)
Core Mathematics (All 4 papers)
Further Pure Mathematics (All 3 papers)
Mechanics (All 3 papers)  


Generally students take 4 subjects and ignore some units or papers but to have a good preparation for what is coming ahead, I have planned to take 5 subjects and not miss out on any unit or paper. However I am unsure whether I need statistics or not. I have understood it plays an important part in Quantum Physics (Feynman diagrams for one) but am unsure if it is really that important or not (3 more papers).  

Recently, my grandfather's school friend came to visit. Despite being a geologist, he had sound knowledge of Quantum Physics (But not of the education system). He advised me to not drop Biology for my O-levels as it will play an important part in the 'Theory of Everything'. I did decide to appear for Biology in my O-levels but should I also take it for my A-level examinations? (5 more units)  

P.S. Each unit requires one paper so I may have to give 28 papers (generally people give 11 papers). If you want to learn more about A-levels click here.

This may seem like personal advice but it will actually help many more students out in the world who plan to make a career out of Quantum Physics. Any help would be appreciated!
Look at the subjects required by a university that offers Quantum Physics and that you'd like to attend. Study the subjects they require.

You'll perhaps be surprised that universities don't require all the subjects you've listed. These subjects are nonetheless useful, they just aren't absolutely necessary, moreover, universities know that students have limited study time. Important aspects of subjects that you don't study will be covered at university. (Furthermore, you can study any aspects that you consider important, but aren't covered.)
