This
is a subject where strategising becomes paramount; since the expanse of
the syllabus itself appears insurmountable. Since you are preparing for
exam purposes here and your primary objective is not, presumably, the 'love of learning' , it becomes important to begin, as I like to put it, backwards.
It's best to analyse the question papers spanning at least a decade;
questions before that are too simplistic to have a fair chance of
appearing in the same form again. So, I would suggest compartmentalising
questions based on chronology. That gives us a fairly expansive scale
of topics to focus on. Second, when preparing a particular topic from a
book or notes, it's important to cover it in entirety-- i.e. think of
all possible aspects of a situation that you can be questioned on. Apart
from facts, focus on 'whys'-- why civilisations crumbled, how different
was their end to another's end. 'How' religious policies contributed to
administration, art and architecture. Focus on analytical questions,
but be clear about facts. Only when there is clarity of facts relating
to different periods can you handle a question that seeks to highlight
the differences and similarities therein. You must be clear in your head
what the basic differences between different civilisations are. This
suggests a panoramic view of history along with some microscopic
treatment. Last year, there were some descriptive questions like
Khilji's market reforms, etc-- and these are very standard questions
that serve as bonus for an exam-taker. Don't be caught off-guard on such
questions.
For books, I began with 'Modern India' by Bipin Chandra, supplemented by
'India's struggle for Independence' by Bipin Chandra, Mukherjee,
Panikkar. Spectrum's book on Modern India that people use for the
prelims is also a storehouse of facts! For Ancient India, I referred to
'Ancient India' by R.S. Sharma (a wonderfully concise book where every
single word is important) and supplemented sparsely by 'The Wonder that
was India' by A.L. Basham. Romila Thapar's treatment of 'Ashoka' is
venerated in Indian historiography. For Medieval India, I found Satish
Chandra's two volumes on Medieval India quite sufficient.
Apart from this, another famous standard text is 'An Advanced History of India' by Majumdar, Raychaudhuri and Dutta.
Personally, I got some history notes from Mr. Hemant Jha in Delhi. I
found them very useful for filling in important gaps in my knowledge. He
covers different aspects of topics and questions remarkably well, with
regard to extra information and facts. Be aware though, you should be
reading standard texts for improving your answer-writing abilities.
As a part of my strategy, I covered the Indian History very exhaustively
and was a little selective for World History. I do not necessarily
recommend this, since it is generally thought that the questions on
World History are more straightforward than questions on Modern India. I
did so because my comfort level with Indian History was greater and I
felt confident of being able to tackle tricky questions. In my selective
studies on World History, i followed Mr. Hemant Jha's notes as well as
'Modern World' by K. Krishna Reddy. There are other better books, you
should google and look some of those up. I focussed on European History
and the Revolutions in particular as I saw a repetition of questions in
these topics.
For Map, there are books available in the market with a large number of
map sites and I'm afraid there's no short cut there. You really have to
learn to mark all of them on the map and learn atleast 3 things about
each place.
Finally, remember to set targets and achieve daily goals! Anything left
over tends to add up dangerously in History. Remember you will be
writing 4-5 page answers, and when you have covered an 'aspect' of a
question that satisfies that word limit, move on. You're not here to do
specialised research on one particular area. While answering questions,
your introduction and conclusion should be impressive. While I
personally used my introduction to explain the setting and context of
the question, I used my conclusion to summarise my answer and place into
perspective the direction that my answer took. Make sure it's
insightful; that's half the battle won! All the best to everyone!
