Why skip trains and boats problems?

They are not in the official TNPSC Group 4 topic list. Preparation imported from bank-exam books spends hours on questions this paper doesn't ask.

TNPSC Aptitude & Reasoning: The Official 16 Topics Only

The official aptitude list is short, and that is the strategy: refuse to prepare anything not on it. No trains, no boats, no clocks, they are other exams' topics.

Step 1
Drill the arithmetic core
Simplification, percentage, HCF/LCM, ratio, simple and compound interest, area, volume, time and work, the complete official list. Fifteen problems a day rotates through all of it weekly.
Step 2
Learn fraction-percentage fluency
1/8 = 12.5% style conversions cut solving time in half across percentage, interest and ratio questions, the single highest-value aptitude skill.
Step 3
Pattern-train the reasoning six
Logical reasoning, puzzles, dice, visual reasoning, alphanumeric series, number series. Each has 3-4 recurring formats; recognition beats derivation under time.
Step 4
Practice at exam arithmetic, by hand
No calculators in the hall. All practice on paper, mental math first, matches the condition you will score under.
