    I m doing my Graduation now(my subjcts are Chemistry,Zoology and Environmental Science)..
    I m confused to take my honours subject since I m not sure whether Environmental Science degree students can apply for the UPSC Indian Forest Service.
    I wanted to try n crack IFS.So,kindly let me know if Env.Sc students can try this exam or not.
    Anticipating ur quick reply..
    Thank U…

    Dear Sir,
    I am a graduate of Veterinary Science and Animal Husbandry and a post graduate in MBA with specialization in Environment Management & Forestry. Sir, I am planning to appear for IFS exams 2013, but due to lack of study material i am planning to opt Zoology and Botany. Can i can clear the exams with the two subjects? Moreover Can you just provide some good books for both the subjects please. And please suggest me about the preparation time also as i am doing a contractual job. Please reply me soon…
