British history is good one but its better if you may go with psychology... Geography will be a little difficult...

British history needs strong power of memorization/ratta as one have to go through with the strange names of kings and most are similar with each other which is totally confusing...I totally agreed with SEHER BANO's views in one of the above posts. please have a look at that.

While psychology is conceptual and easy to grasp, one has to extract examples from daily life, you can support your answer with examples whcih everyone met in his/her childhood,adulthood etc...

For geography one has to go through maps in detail. While going with psychology or geography one is able to attempt some of eds mcqs in a very easy way...

So i will strongly recommend you to go with Psychology... No matter you have science background or not...as you do not have the background regarding British history...Further i will add that all these three subjects are considered high scoring as topper of 2011 was having all these three subjects in his combination...So go with anyone of these after a comprehensive analysis, keeping in mind your aptitude and interests of grasping one...

I will appreciate if you may share your other subjects as well.
