Answer:
LOTD means LETTER OF THE DAY.
Step-by-step explanation:
When taking an exam, the LOTD method implies that you select a letter from A to D and take it as the only letter to answer those questions that you are not sure of your answer.
This method stands out as a good strategy since instead of choosing an answer at random, you will be choosing one of every four correct answers.
However, the best method is always going to be to study hard for your exams so that you don't have to face questions that you can't answer.
