Even students who understand the concepts of Tick Tick Tick often lose marks on exams due to simple, avoidable errors.

Top Mistakes to Avoid in Exams

Order of Operations (PEMDAS/BODMAS)

Performing addition or subtraction before resolving multiplication, division, or parentheses.

Unbalanced Equations

Decimal Point Shifts

Misplacing the decimal dot when converting percentages or multiplying by factors of ten.

How to Eliminate Silly Mistakes

• Highlight Key Numbers: Circle values and units in the question text before writing your answer.
• Check Your Signs Twice: When moving terms across the equals sign, verify that you inverted the sign (e.g. addition to subtraction).
• Estimate First: Work out an approximate answer mentally. If your detailed calculation is completely different, you likely made a basic decimal error.
