hey Anup,
No need to get worried, we are here to help you. Just get relaxed.
So 1st of all you need to analyze yourself that what you want to do or what you want to become.
So the very 1st step to self analyze.
2ndly you need to know the strong field of your study where you can do better in your career.
So in my point of view, these 2 ways can be used to decide the career path.
However, I am describing some of the careers paths from which you can decide yours from your interest factor

1.Medical line
Basically, in this course, you need biology the most and there is no requirement of mathematics. You have to qualify the NEET exam to build your career in this line. In NEET, there are mainly 3 sections including biology physics and chemistry. You will get 45 qns from physics and 45 qns from chemistry whereas you will get 90 qns from biology which will include both botany and zoology. However, the total time period will be 3 hours. And also you can get admission through the entrance examination known as AIIMS.
2.Engineering line
In this career path mathematics is the most important one. You have to qualify the JEE MAINS exam to study in this path. However, there are some other private college entrance exams through which you can get admission. In this exam, you will have to face qns from mathematics physics and chemistry.
3.BSc line
In this type, you will get admission on the basis of your 12th result and merit list provided by the colleges you have applied. Here there is no limitation in what you have as your subject in 12th. You will get admission according to your wish. There are many streams like mathematics, physics, chemistry, botany, zoology, microbiology etc.
4.Research line
In this path, you can have either both or any one or mandatory both that depend upon the entrance exam you are giving. There are certain entrance exams such as KVPY, NEST where you have to face the qns from both math and biology along with physics and chemistry but you have to answer either in any 3 in NEST but in KVPY you have attend all of them.

I have given you some possible cases. Hope you have got your answer. If not do no hesitate to inform me. I will help you with more information.
Thank you
