hi and aoa.....
british history is a scoring subject no doubt about that.....but one should not ecpect to get 140-150 without putting in much effort....it is said that it is scorig because you don't have to put in a alot of effort in preparing it as in indo-pak history and secondly there are only about 100 students who opt fot british history...
studing chaurasia's book is not a good idea as one should study a good book rather than an easy one....british history by south-gate and british history by thomas are good options
