My english is not so good can i prepare IAS examination and how i prepared well

If your english is not good then no problem.... Exam of IAS can be given as a Hindi Medium candidate from IAS(pre) to IAS interview... but in IAS (pre)/CSAT there will be some portion on General English in paper 2 upto 10th level approx 20-30%.. so no any problem for you... ?? ?? ??? PREPRATION ??

you concentrate on your reading and writing skills in the initial stages.there can be a very great improvement,as you read and read and so ,inculcate good reading habit.it comes mainly through putting your skill into practice.increase your exposure to english as much as possible and it brigs in subs

you should read CSR magazine regularly , for you can improve english , update current affairs, you also need to read general study
