    Thanks madam but 1 dout regarding to OLD NCERT IT is need to study old geography ncert because its get difficult in Maharashtra and if not need to read old book which book is sufficient to pre and specially main exam

    1. Demos

      As far as GS is concerned, mam’s lectures + NCERT(new) and GCL + some youtube videos here and there for some selective topics would be enough.
      Nothing more than that is needed .
      Just keep on revising as much as possible, that’s the key.

  2. Student

    Madam Please Tell me whether you are covering all topics for Geography Optional Paper ?

  6. SANDY

    Hello mam …..there is one doubt …
    u said that there is high pressure in the eye of cyclone….but it is well known that the lowest pressure known on the earth is the centre of a tropical cyclone….how could both the contradictory statement be correct. …

    1. Roshani

      Yes Sandy,

      you are right. I also have same doubt. In wikipedia, It shows that there is low pressure in the eye of tropical cyclone.

      Rajtanil madam, please clear the doubt.

  7. Raj

    Madam, I’m short of words to appreciate the great work you are doing.
    But I sincerely request you to please understand that there are many people (like me) who are relying on 2G internet connection (most of them by force and some by choice) for getting reading materials. I’m religiously following this website for getting the reading materials in text. I know I’m asking for much, but if you can really take out time then please put up the content in simple text (as like other Mrunal sir’s articles).
