Shortcuts for Competitive Exam Problem Solving
In competitive exams like NEAT or IAT, time is of the essence. You need to be able to solve problems quickly. If you approach a problem from an energy conservation standpoint, you can solve it in just 30 seconds. Let's say we have a ball with mass 'm' that has potential and kinetic energy. If we equate the total energy, we get:
- Total energy initial = Total energy final
- 0 = Kinetic energy initial + Potential energy initial = Kinetic energy final + Potential energy final
- 0 = 1/2 mv2 + 0 = 100(1/2 mv2) + 1/2 mv2
- 225 = v2
- v = 15 m/s
Learning shortcuts like this can be very useful for competitive exams where time is limited. The wave allergy Sampath teaches is amazing and very relatable. Watching videos on difficult topics is helpful for understanding and his unique teaching style makes everything seem simple. Overall, finding ways to save time during exams is crucial.
