Microbiology

The first thing that you need is to ask yourself, because if you can handle the Formulas in Physics and Mathematics, then you should surely go with the Physics, Chemistry and Mathematics stream. If you are a proper money man and want to become a business man, then you should choose Commerce as your stream, because it will surely help you in your future. I chose PCM stream in class 12th and have got lots of opportunities in the field of education. I am not demotivating the commerce passion or any kind of arts passion I am just so satisfied with the science stream I have. If you will choose the commerce stream and have the passion in computers, then you can go for BCA from any university and If you have science then no paths are closed to you. Science is not a subject it is the way to help you achieve the best knowledge that is present in the nature and if you are happy with the business things then you can surely go with the commerce.
So, at last in my answer I am also confused which one to advice it to you because it only depends on you which one you want to pursue and want to make your career in. So, all the best.
