Author questions are pure memory, so group them. Jawaharlal Nehru wrote The Discovery of India and Glimpses of World History; Dr B R Ambedkar wrote Annihilation of Caste; Kautilya wrote the Arthashastra.
Among literary classics, Kalidasa wrote Abhijnana Shakuntalam, Rabindranath Tagore wrote Gitanjali, and R K Narayan created Malgudi.
Also track autobiographies and their subjects, since exams often pair a title with the wrong author as a distractor.
