Suggestions for students preparing for the exams

Before going to the Examination Hall

1. Avoid indigestible food, excessive liquids and stimulants like cola, coffee or tea in the previous night.
2. Avoid late night reading.
3. Sleep for six hours at least, to get enough rest.
4. Avoid discussion about previous papers.
5. Plan some relaxation in the morning like listening to light music or going for a short walk or a jog for 15 to 20 minutes.
6. Do not attempt any new revision topics on the day of examination.
7. Eat light food with good nutritive value well before you start from home on the way to examination hall. Keep a small water bottle along with to keep you well hydrated.

In the Examination Hall

1. Minimize waiting time outside the examination hall. It is always good to have known the exact examination hall and seat on the previous day.
2. Walk straight into examination hall on the day of examination.
3. Avoid anxiety provoking discussions with friends e.g. discussion on topics or questions or nervous feelings you have, etc.
4. Practice positive self-statements like "I am going to do well", "I am well prepared for this examination', ‘I have come here to pass the examination with good grades’.

 In the Examination Seat
1. Settle and compose yourself.
2. Layout your equipment. e.g. pen, pencil, compass etc at leisure with cool mind.
3. Take fifteen minutes to read the paper and check instructions carefully and then underline key words in questions in your mind and plan.
4. Try to write legibly.
5. Leave space after each answer.
6. Select the question you know the answer best.
7. Write simply in short sentences, with correct spellings.
8. Avoid long background introductions in your answers.
9. Do not worry about the number of supplementary sheets used by the other examinees. Just concentrate on your own job.
10. Plan your time - drive the time according to the marks allocated to each question.
11. Stick to your time budget - try to keep ten minutes time at the end so as to permit you to tie supplementary, check roll no. etc.
12. If you are running out of time - remember that two half answered questions fetch more marks than only one fully answered question. So never leave any question unattempted.
13. Always leave fifteen minutes in the end to check your answers. This strategy helps to make minor changes, recheck any inadvertent omissions and adds to the mental peace for further examination papers.
Wish you all the very best for the examinations. It's absolutely fine and normal to be nervous. But your nervousness must never hold you back from performing your part.
All is well! Learn to Smile through Stress. Stay calm, be cool, be healthy, eat healthy, prepare well, do well and then wait for the magic to unfold. The World's all yours ... Go, Win it !

Wishing you a successful life!

Happy Birthday to Srinivasa Ramanujan

Today is the 129th birth anniversary of great Indian Mathematician Srinivasa Ramanujan and so is National Mathematics Day.

Srinivasa Ramanujan was born on 22 December 1887 in Erode, Tamil Nadu. He is a man known for his work done in the field of mathematics. And that too with no formal training of that subject which others are getting in European countries.  Ramanujan developed his own mathematical research in isolation. Some extraordinary contribution done by him in the field of mathematics are – mathematical analysis, number theory, infinite series, and continued fractions. Along with this, the legend has provided many theorems.
He was enrolled into Telegu School, but found it too tiring and uninteresting to attend school and mostly he use to ran away from there. Later in 1904, he graduated from Town Higher Secondary School. He also received a scholarship to study at Government Arts College in Kumbakonam. During his studies he was so influenced by studying mathematics that he could not focus on any other subject and failed in all of them. This resulted him in losing the scholarship. Later, without any degree, he left the college and continued to pursue independent research in mathematics.
His unconditional love for mathematics was driving him to develop new things for that subject, but to support his livelihood he was working as a clerk in the Accountant-General's office at the Madras Port Trust Office. He kept working on inventing new mathematical theorems and continuously tried contacting the experts from west.   G.H. Hardy, an academician at the University of Cambridge, recognized the brilliant work produced by Ramanujan and invited him to visit and work with him at Cambridge. Here, Ramanujan became a Fellow of the Royal Society and a Fellow of Trinity College, Cambridge.
Some of the known works, produced by this great mind, are - Landau–Ramanujan constant, Mock theta functions, Ramanujan conjecture, Ramanujan prime, Ramanujan theta function, Ramanujan's sum, Rogers–Ramanujan identities and Ramanujan's master theorem.
Ramanujan died on 26th April, 1920, when he was only 32 years of age. In this short life he gave around 3900 results, mostly equations and identities and almost all of them prove to be correct and original.
G. H. Hardy liked to rank mathematicians on a scale of 1 to 100, and he gave himself 25, Littlewood 30, David Hilbert 80, and Ramanujan 100, which shows just how great Ramanujan was.
The Indian mathematical genius Srinivasa Ramanujan was born on 22 December 1887. It was in recognition of his contribution to mathematics the Government of India decided to celebrate Ramanujan's birthday as the National Mathematics Day every year and to celebrate 2012 as the National Mathematical Year.

Seventh Intra School Mathematics Olympiad - Solution Key

Dear Readers,
Mathematics, often called as language of nature has become an integral part of everyone’s life. In today's highly competitive world, one has to bear a lot of mental stress and also have to get involved in so many things in order to acquire knowledge. This is where co-scholastic activities play a very significant role. They provide the much needed exposure for a student.
CRPF Public School has fulfilled its motto of striving towards excellence by organizing and successfully completing its Seventh Intra School Mathematics Olympiad on 22 November 2016. Around 300 students enthusiastically participated in the Olympiad held in school premises.
Such Olympiads and events provide a great and extended platform for the students to nurture and showcase their ability and talent. It was a towering learning experience for the students of the school from classes IV to XII. To encourage students, merit certificates will be given to those scoring at least 60% along with the normal prizes for the top scorers.
We hope that all the participating students must have done well in the exam. To access your performance, check out the solution keys of the question papers below:-
