See in Case of NEET you are required to pass the Physics /Chemistry /Biology compulsorily all the subjects and the aggregate must be greater than 50% for PCB. So if you fail in chemistry you are not eligible for NEET.

For Paramedical Courses, the student needs to pass Physics/Chemistry/Biology for most of the specific UG courses, for that also you won't be eligible. Apart from this in Pharmaceuticals as well the chemistry comes under the eligible criteria. So this fields you are ineligible.

But you can take admission in BSc courses which don't requires Chemistry for example, you can take admission in BSc Hons in Physics/BSc in Biology (in most colleges chemistry isn't required)/BSc Hons in Nutrition etc.
