Hello aspirant

If you are interested to go for medical field then you must appear for NEET and then if you choose maths also then only you can go for jee main. So it's important for you to decide first and then focus on your aim.If you want to become a doctor then work hard and prepare for NEET well. Because maths require lot of practice and for neet your biology must be strong. Also there is nit much time this year , that also matters. Hence according to me it will be difficult to prepare for both biology and maths. However its finally your decision.  Good luck!
