7 Study Hacks To Help Crack IIT-JEE


Over 10,00,000 students take IIT-JEE each year, but only a small percentile make it. The most essential step in cracking any competitive examination is to believe that you have it in you to realize your dream. With this perspective, as you prepare for IIT-JEE means you’ve won half the battle.

Now, let’s find out how to win the other half:

  • Plan a study timetable. One of the challenges aspirants face is the problem of managing their time effectively. The best way to do this is to plan your study well in advance, and then to stick to the plan consistently. Pay judicious attention to the three subjects: Physics, Chemistry, and Mathematics.
  • Start with the basics. Take special care in ensuring that all your basics are clear. Focus on topics you have trouble with, and be persistent in getting the basics cleared for the same.
  • Time yourself. This will help you be mindful of the time barrier. Every question that you attempt should be completed within the stipulated time.
  • Practice self-reliance and never leave a question half-solved. Don’t jump to the solutions section before trying to get the right answer yourself a few times. This will teach you self-reliance, and help you with any problems you might have in the basic understanding of the question and concepts.
  • Have a conceptual approach. While reading a question carefully before attempting is expected, it’s also important to look for the concept the question needs you to apply when attempting to solve it. This will help you understand the problem to be solved in a leveled and proper manner.
  • Avoid burning the midnight oil. Our minds are the freshest after we sleep, and studies have shown that we retain information better when we study after a good night’s sleep. Rise at 6 AM and sleep at 11 PM. This will keep your brain activity at maximum in the mornings, and will help you on the day that you take the exam.
  • Take 2 hours each day to do something you enjoy. Unwinding after long hours of studying is as important as regularity and consistency in preparation. Giving yourself time to relax with a hobby or sport of your choice will help you de-stress and avoid anxiety before the exam.

With these 7 steps, you’ll be better prepared to take the IIT-JEE exam. Do you have any personal favourite study hacks of your own? Share them with us in the comments. 🙂

Traffic Management: The Journey So Far


Have you ever found yourself; while waiting at a traffic signal, watching the timer count down to zero; wondering precisely why traffic signals last as long as they do? The numbers are fairly inane. The signal near my house lasts for 53 seconds, 53! Why not a minute, or 10 seconds. Well, the answer to this and a lot of other questions regarding traffic lie in the realm of Traffic Engineering. Today we will discuss a few dimensions that make up the patchwork quilt that is this hybrid discipline. Traffic engineering considers two primary problems; How to reduce congestion on the roads and how to reduce accidents.

Of course, these problems have varied nuances. How does one reduce congestion while still maintaining a reasonable speed limit, can one reduce the amount of time that drivers have to wait at traffic signals, toll bridges etc. The science is a mixture of mathematics, physics and human psychology.

One of the fundamental concepts is the lane-flow equation. The relationship between lane flow (Q, vehicles per hour), maximum speed (V, kilometers per hour) and density (K, vehicles per kilometer) is Q=K.V

Observation suggests that up to a maximum flow, speed does not decline while density increases. However, above a critical threshold, increased density reduces speed. Additionally, beyond a further threshold, increased density reduces flow as well.

Road systems are designed using queuing theory. Queuing theory is the mathematical modeling of lines and a sequence of interconnected queues is a queuing network. When an object (in this case a car) crosses a queuing node(intersection, traffic light etc) it can either proceed to the next queue or leave the network. Once a network has been designed, it can be optimized on the basis of the lane flow equation. The optimization rule used is usually Kerners Breakdown Minimization principal.

The final network may be improved further by three-phase traffic analysis. This considers the physics of traffic jams. The theory states that there are 3 states that may exist; Free flow, synchronized flow and wide moving jam. The theory considers breakdowns that may occur when transitioning from one state to another.

Traffic management is a really exhilarating field, particularly for math junkies, like this author. 🙂
