Hello dear student,
I think you are not aware that ews is a category for the students belonging general category and whose parents income is less than 8 lacs per annum so they do not belong from SC ST or OBC category. So if you belong from EWS category that means you are a general category student so you need marks which is 50% aggregate in physics chemistry and biology to be eligible to give Neet . you are aiming for whatsoever course under Neet but this is the eligibility criteria to give Neet exam. Dear student I am really sorry telling you that you will not be able to give Neet as you have 49% aggregate in pcb section.
I hope this information is helpful to you.
Best wishes
