Every year with board exams approaching, schools and colleges work hard to prepare their students While educational institutions compete hard to ensure good results, they also make sure their student don’t face stress. The stress that the Board exams have started creating is a recent phenomenon. which has been created due to the highly competitive world we are heading into. Students often make securing high marks in boards as a life and death issue. This is also because the cut-off d many colleges is so high that many children miss their chance of studying in it and, therefore, art under pressure from parents, family and friends. All these pressures affect the mental health of children as they become nervous before the exams so much so they become even mentally blank and forget as they appear for a paper. Therefore, counselling before the board exams is very essential for better performance and health of the children. These counselling sessions give children some mental support and strength to use their energy in a positive manner. Most schools are now taking to these counselling sessions for better results. These counselling sessions are not only for students but also for parents. A counsellor in these sessions does not only talk and try to de-stress the child but also guides him too long to adopt a better lifestyle. The only thing that can help children deal with stress and not lose their important years of life and innocence of childhood counselling before board exams are important.

In English While humans and terrestrial animals breathe oxygen from the air, aquatic animals use oxygen that is dissolved in water. An aquatic animal breathes by absorbing free oxygen into its blood through its gills or directly through its body surface.

Let us assume √5 is rational number which can be written in the form p/q there for √5=p/q (where p and q are co-prime integer and q is not equal to 0) √5q=p --equation first squareing both side 5q²=p² here five divides p² Therefore 5 also divides p let p = 5C putting value of p is equation first equation √5q= 5C squaring both side 5q² = 25c² q²=5c² q²/5 =c² Here 5 divides q² Therefore 5 also divides q Here we can see 5 divides both integer p and q but it contradicts that p and q are co prime integer this contradiction arising due to our wrong assumption therefore √ 5 is irrational number.
