I think you people are tackling this from the wrong direction. If you want better marks in English, I suggest studying the core texts thoroughly first. From there, you'll be able to extract issues or 'themes' related to the concept of 'Belonging' and find texts that not entirely focus on 'Belonging', but the fundamentally interwoven ideas within.
For example, the renowned notion of 'Change' was what I studied last year. At first, we were pretty much like you guys are now (no offense), believing that we should take advantage and start looking for related material right away. All we had was a very basic idea, in that we thought we could do pretty much anything as everything changes. However, with further insight into Keats' poems, there was a pervading sense of his unwillingness to die as a result of 'change'. Using this as a basis, I started searching for related material and found Bicentennial Man; something I reckon is somewhat different, and works perfectly.
So anyway, I'm just saying that, unless you people already have an extremely in-depth idea of what 'Belonging' is, don't go rushing in. Take the time to really generate your own perception on your core texts and, using that as a backbone, find suitable, unique related texts that reinforce your perspective of the AOS.
