Save 30–60 seconds per question — these tricks separate toppers from the rest
× 11 Trick:
25 × 11 → write 2_5, middle = 2+5 = 7 → 275
47 × 11 → 4_7, mid = 11, carry → 517
× 25 Trick:
Any number × 25 = (number × 100) ÷ 4
36 × 25 = 3600 ÷ 4 = 900
× 125 Trick:
Any number × 125 = (number × 1000) ÷ 8
48 × 125 = 48000 ÷ 8 = 6000
× 99 / × 999 Trick:
n × 99 = n × 100 − n
37 × 99 = 3700 − 37 = 3663
Numbers ending in 5:
n5² → (n × (n+1)) then append 25
35² → 3×4=12 → 1225
75² → 7×8=56 → 5625
Near 50 squaring:
(50±n)² = (25±n) | n²
47² = (25−3) | 3² = 22|09 = 2209
53² = (25+3) | 3² = 28|09 = 2809
Near 100 squaring:
(100±n)² = (100±2n) | n²
96² = (100−8) | 16 = 92|16 = 9216
104² = (100+8) | 16 = 108|16 = 10816
💡 Example:
37.5% of 480 = 480 × 3 ÷ 8 = 1440 ÷ 8 = 180
First n natural numbers:
1+2+…+n = n(n+1)/2
1 to 100 = 100×101/2 = 5050
First n odd numbers:
1+3+5+…+(2n−1) = n²
First 9 odds = 9² = 81
First n even numbers:
2+4+6+…+2n = n(n+1)
First 10 evens = 10×11 = 110
First n perfect squares:
1²+2²+…+n² = n(n+1)(2n+1)/6
First n cubes:
1³+2³+…+n³ = [n(n+1)/2]²

Final review
The 90-Second Rule
If you haven't cracked a question in 90 seconds, mark it and move on. Return if time permits. Time lost on hard questions = easy questions left unattempted.
Elimination First
In MCQs, eliminate 2 wrong options before calculating. Often reduces to a 50-50 guess which saves 40–60 seconds vs full calculation.
Section Order Strategy
Start with your strongest section to build confidence. Save Reading Comprehension for last — it requires fresh mental energy but can be done quickly.
Negative Marking Protocol
Only guess if you can eliminate 2 options. Expected value: 3 options left = attempt (⅓ chance beats −0.25 penalty). 4 options left = skip.
Don't Re-check Easy Questions
Re-checking questions you're confident about wastes 10–15 minutes. Use that time on unattempted questions instead.
Last 5 Minutes
Stop solving new questions. Spend last 5 minutes filling in your best guess for any blank answers (on no-penalty exams) or reviewing flagged ones.
