Why Arithmetic is Your Best Friend
In the TSLPRB Preliminary exam, Arithmetic and Reasoning make up half the paper. In the SI Final Exam, they form an entire 200-mark paper (Paper III). Unlike General Studies, where a question can be infinitely obscure, Arithmetic is bounded by logic. If you know the formula and the shortcut, you get the mark. 100% accuracy is possible.
Core Topics to Master
According to the official TSLPRB syllabus, your focus should be strictly on Commercial Mathematics and basic Mensuration:
- The Big Three: Percentages, Ratio & Proportion, and Averages. (Mastering these makes every other topic easier).
- Interest & Profit: Simple Interest, Compound Interest, Profit & Loss, Discounts.
- Time Dynamics: Time & Work, Work & Wages, Time & Distance (including Trains and Boats).
- Geometry Basics: Mensuration (2D areas and 3D volumes).
The Secret to Speed: Stop Using 'x'
With negative marking (20%) introduced, you cannot afford to waste 3 minutes on a single math problem. You must transition from traditional high-school algebra (using 'x') to ratio-based and percentage-based shortcuts.
