Tips to combat exam stress:
An adequate level of anxiety is good as it motivates the individual to stay focused and give his/her best, but if anxiety is more than the desired level, it impedes performance. I can offer some tips:
Before examination:
  • An effective preparation has to be preceded with a positive attitude coupled with a belief in one's abilities and strengths.
  • An intake of nutritious food rich in vitamin B supplements is vital at this stage as vitamin B helps to improve memory and concentration.
  • One should take mock tests that are based on sample blueprints issued by CBSE and previous years' question papers.
  • One should refrain from use of cell phones and the Internet during study hours.
  • One should concentrate more on the subjects that seem challenging.
  • It is also important to accord some time for relaxation between study hours. This not only gives time for retention but also prevents proactive and retroactive inhibitions.
  • Too many books can result in confusion and hence it is advisable to consult NCERT books and notes prepared earlier.
  • Making a study schedule can immensely helpful especially in terms of time management.
In examination hall:
  • One should be positive and confident during the day of actual examination.
  • One should read the question paper carefully . A good start to a paper is to first choose the answer that one feels the most confident about.This approach will boost the confidence and motivate the examinee to tackle the rest of the questions.
  • The answer must be to the pointed precise.Spending too much time on one question should be avoided.
  • Check answers and make sure that each part of the question has been answered
Examination is comparable to a marathon,which requires slow and steady strides.




The chances finding alien life werw given a boost after Nasa revealed it had found evidence of more than 1,200 planets in orbit far distant stars. 54 may be able to support life!

Astronomers using the Kepler space telescope have found a system of six planets orbiting a rouglly Sun size star named Kepler 11 -- is similar to our own sun 2,000 light years away. All its planets are in orbit too close to the star to hold life as we know it.It validates a powerful new mathod to measure the masses of planets.The five inner planets in the Kepler-11 system range in size from 2.3 to 13.5 times the mass of the earth. They orbit within a region that would fit inside Mercury's orbit of the Sun.
