Marks depend on a number of factors

1-Your knowledge
2-Style of the question paper
3-Examiner's inclinations for that year
4-Destiny...
and so much more

so dont think that going through a particular book would give you 70% or more marks ,be a bit more analytical in your approach and hope for the best.

Horton and hunt is a good book but last year there was a question in sociology paper

How are you different or similar to your parents?Elucidate

Now to attempt it you got to have an understanding of sociology as a subject and you may not find such answers in any book


I think I have written a bit too much but this one just goes out to all people who are eager to know "will they get 70% marks studyin a particular book"
the answer is
YOu may and you may not

"do smart work instead of hardwork" though hardwork is necessary too
