First of all, don't be afraid of these topics! TSD, Time & Work, and Races become much easier once your basics are clear. You don't need to solve every question; you need to learn how to recognise the pattern.
**1. Time, Speed & Distance (TSD) 🏃**
- Remember the basic formula: Speed = Distance/Time.
- Learn unit conversion: km/h to m/s → multiply by 5/18; m/s to km/h → multiply by 18/5.
- For relative speed, use addition when two objects move towards each other and subtraction when they move in the same direction.
- For trains, remember that crossing a pole involves the train's length, while crossing a platform involves train length + platform length.
- Practise average-speed questions carefully. Average speed is not always the arithmetic mean of two speeds.
**2. Time & Work 💪**
- Assume total work as the LCM of the given days whenever possible. This makes calculations easier.
- If A completes a job in 10 days, A's one-day work = 1/10.
- When people work together, add their work rates; when someone undoes the work, subtract their rate.
- Practise efficiency-based questions: if A is twice as efficient as B, A does twice as much work in the same time.
**3. Races 🏁**
- Start with simple questions involving distances, speeds and head starts.
- If two runners have speeds in the ratio 5:4, their distances covered in the same time are also in the ratio 5:4.
- If A beats B by 20 metres in a 100-metre race, A covers 100 m while B covers 80 m in the same time. So their speed ratio is 5:4.
- Focus on understanding the relationship between distance, speed and time instead of memorising too many formulas.
**4. How to improve without getting overwhelmed**
1. Learn the concepts from one reliable source.
2. Solve 10–15 basic questions without a timer.
3. Move to CAT-level questions once the basics are clear.
4. Maintain a mistake notebook and revisit questions you couldn't solve.
5. After building accuracy, introduce time limits gradually.
**Most importantly:** Don't skip a question just because it belongs to TSD or Time & Work. Read it, identify what is given and what is asked, and try to form an equation. If you are stuck for 2–3 minutes during practice, check the solution and understand the approach.
You don't have to master everything in one day. Give these topics consistent practice for a week, and you'll gradually feel more confident. All the best!
