I do not think I can come up with a "common question" for English, as I will explain below

English is quite different from most other subjects in that it is heavily source-based, both in one's understanding but also in the simple components to a question. I will separate this explanation into two parts: English Literature and English Language (as with GCSE's and up, English is no longer one subject)

With regards to English Literature, there are always two types of questions in exams. These are essay-based questions, touching upon the general themes of the work being studied (ie a novel, set of poems, play etc), and passage-based questions. Both require some level of understanding of the piece of work that has been studied by the students and therefore you cannot come up with a "common question". With essay-based questions, the recurring question is often one regarding the key themes of the play, but for obvious reasons I cannot answer that in this section without a relevant piece to be writing about.

For English Language, I've found that questions are heavily dependant on the exam board, as while CIE focuses narrowly on different aspects of linguistics at A-Level (such as "Language and Empowerment"), AQA appeared to use much broader questions encompassing many different aspects into one overall answer.

I apologise for this, but I don't think you can come up with a "common question" for English A-Level. On that note, I'd just like to reiterate that I am more than happy to tutor at other levels in English, or indeed with the LNAT examination as I have indicated.
