Error Spotting
Error Spotting is a vital part of the English section in competitive exams like UPSC. It tests your ability to find grammatical mistakes in a sentence. A sentence is usually broken into four or five parts. You have to identify which part has a mistake. If the sentence has no mistake, you select the 'No Error' option. This topic covers many grammar rules, including nouns, pronouns, verbs, tenses, and prepositions.
