Common Mistakes and Exam Tips

Common Pitfalls

• Subject-Verb Agreement: Ensure that the subject and verb agree in number. For example, when the subject consists of two or more nouns connected by 'and', use a plural verb.
• Indefinite Pronouns: Remember that indefinite pronouns like 'each', 'either', 'every', 'much', and 'neither' always require singular verbs.
• Collective Nouns: Collective nouns can be singular or plural depending on context. If the group acts as one unit, use a singular verb.
• Nouns Ending in 's': Some nouns that appear plural but refer to one thing are singular and take a singular verb (e.g., 'Mathematics is an interesting subject').
• Phrasal Verbs: Be careful with phrasal verbs and their meanings; ensure you understand their usage in context.

Tips

• Read Instructions Carefully: Always read the exam instructions thoroughly to avoid misunderstandings.
• Practice Subject-Verb Agreement: Regularly practice identifying subjects and their corresponding verbs in sentences to strengthen your understanding.
• Use Binomials Correctly: Familiarize yourself with common binomials and their meanings to enhance your writing.
• Check for Onomatopoeia: When writing creatively, use onomatopoeic words effectively to enhance descriptions.
• Stay Organized: Keep your answers structured and organized to make it easier for the examiner to follow your thoughts.
