📘 How to Attempt These LEA Based MCQs

Follow these simple steps to simulate exam conditions, boost accuracy, and learn from mistakes effectively.

  1. Read each question carefully. Look for keywords like “primary,” “most common,” or “best suited.”
  2. Use the elimination method. Cross out obviously wrong options first to narrow choices.
  3. Time management: Aim for 1 minute per question (total 50 minutes). Mark hard questions and return to them later.
  4. Think conceptually. LEA questions often test application — ask yourself why an answer fits.
  5. Keep calculations minimal. Most MCQs are conceptual; when calculations appear, write steps clearly.
  6. After finishing, review answers. Check the answer key only after completing the whole test to assess time and accuracy.
  7. Create a revision list. Note down topics you missed and review them in short, focused sessions.
Quick tips:
  • Answer easy questions first to secure marks quickly.
  • For disease questions, remember causative agents (virus/bacteria/protozoa) and prevention methods (vaccination/biosecurity).
  • Memorize common breeds, top-producing regions, and key lab tests (e.g., CMT for mastitis).

Tip: Repeat the quiz weekly and track progress. Consistent practice beats last-minute cramming.
