Wider Reading?

Is wider reading really that beneficial in subjects like Psychology and History? My teachers say it is good to do wider reading but I do not know what to read.. Does wider reading mean read only books or can wider reading come under reading other textbooks not given by the teacher?

Also does anyone have any suggestions for wider reading on Psychology AQA A AS Level, The Russian Revolution and Britain and the Nationalist Challenge in India? (History Edexcel)

Wider reading is beneficial and to be perfectly honest should be obligatory for all subjects. How can you be sure that you like your subject if you've not even taken the effort to go beyond the curriculum? Don't read textbooks, they're boring. I don't know much about psychology or history but there are lots of good books on all subjects that you should be able to understand. Go to your local Waterstones or something and they'll have lots of interesting psychology and history books.

Don't be constrained by the curriculum. I promise you'll enjoy your subject a lot more if you take an extracurricular interest in it.

did u do biology? and did u do wider reading for that? if so what books?
