Exam Tips & Common Mistakes
Common Mistakes and Exam Tips
Common Pitfalls
- Misunderstanding Merged Words: Students often confuse merged words with compound words. Merged words are formed by combining parts of two words, such as 'intercom' from 'internal' and 'communication'.
- Incorrect Use of Adjectives: Students may use adjectives that do not fit the context of the sentence. For example, using 'narrow' to describe a 'plan' may not be appropriate.
- Ignoring Vowel Insertion: When completing words by inserting vowels, students sometimes overlook the meanings provided, leading to incorrect answers.
- Confusing Acronyms and Initialisms: Students might not recognize that acronyms are pronounced as words (e.g., ISRO) while initialisms are pronounced letter by letter (e.g., FBI).
- Misapplying Suffixes: When forming words with suffixes like '-ship', '-ment', and '-hood', students may not apply them correctly, resulting in non-existent words.
Tips for Avoiding Mistakes
- Practice Merged Words: Familiarize yourself with examples of merged words and their meanings to avoid confusion.
- Contextual Understanding: Always consider the context when choosing adjectives to ensure they accurately describe the nouns they modify.
- Refer to Meanings: When completing words with vowels, refer to the meanings to guide your choices.
- Learn Acronyms: Make a list of common acronyms and their meanings to distinguish them from initialisms.
