hi,

see students of background of bsc /msc physics, engineering degree course holders like mechanical, aerospace engineering, electronics and communication engineers has wide scope to work in space technology platform, however at this course mathematics is really important and it some times mandatory to have in 12th course to admission in various masters courses. so if you not having mathematics in 12th course make you not eligible to pursue certain courses. however you may study in your own stream like  bachelors course in chemistry, biology, zoology etc and may become a scientist in your own field.
