Hey Rahul,

As far as general science is concerned it is needed in most of the government entrance examinations, it is sort of a must for every government exam. To name a few examinations, general science is required for the UPSC, IRS exams and also if you are looking for government teaching jobs genral science is required as well. So these are only the few exams that i have mentioned here, but it is required in number of them, so you must have knowledge of general science if you want to get through these examinations. Hope this helps, thank you for asking question here at careers360.
