HOW TO SCORE 100 % IN MATHEMATICS?

So, you want to score Cent percent in your mathematics Tests.
GREAT !
 HERE ARE THE STEP YOU SHOULD FOLLOW TO ACHIEVE A PERFECT SCORE

Our Student, who told us how he achieved a Perfect score both in class X and XII Public Examination, has enumerated the steps he had taken.
1. Mathematics is not hard; all it requires is understanding and PLENTY of Practice.
2. Read- Understand- look at the examples and solved questions and then get on to practice.
3. Break down the problems into the following steps.
a) Step – 1. What is given? (The data, facts, statement)
b) Step – 2. What is asked? (i.e. what is required to be found out?)
c) Step – 3. Is any conversion of the units required? (if yes, convert it)
d) Step - 4.  What is /are the formula to be used?
e) Step - 5. Working step by step (If algebra be careful about the signs)
f) Step – 6. Once you get the answer, check back, to ensure it is correct.

To start with write down the formula/ rules given in the chapter Daily this has to be done every day for 30 days, there after once a week would do.
This practice helps, in Recollect, Re-call, Refresh and Remember.

While in School- Listen to the instructor- clear the doubts then and there, do not worry about your peers, if you feel shy are scared you will never be able to score.
NO DOUBT IS TO BE CARRIED HOME.

Remember – Mathematics can be read like other subjects, it requires constant and concentrated practice.
Your mind will recall only by repeated practice.
There may be a number of methods to solve a problem. If you want to score a perfect 10, then you must know all the possible ways to solve the problem.
Short cuts can be learned and practiced in order to reduce the time.
SPEED and ACCURACY is needed to tackle any Competitive Examination.

At Home: Revise and re do the problems. Let us say if one chapter has about 30 questions. You must solve all the 30 questions, without leaving even a single problem
This gives confidence to you. (Re assurance of your mind yes I CAN)
If you are unable to solve a particular problem, you can ask your friend, if you have an internet, you may Google it.
In the class ask your teacher if you have done it correctly.
Step by step solving the problem helps you to understand where you might have gone wrong.
ALGEBRA- Take care to check and re-check the signs
Trigonometry- There are more no of ways to solve the problem, if not one method the other method would be of help. Ie. TAN can be written as SIN/ COS. And like wise Sin²Î˜+ Cos² Θ = 1
Or 1- Sin²Î˜ = Cos² Θ or  1- Cos² Θ= Sin²Î˜


Solving word problems
Example: A man bought ¾ kg of sugar from a shop and ½ kg from another shop. He used 2/3 kg sugar. How much sugar is left with him?
Now let us solve this problem by using the Step- by Step method.

Step-1
What is Given?
a) Qty of Sugar purchased ¾ kg and ½ kg
b) Qty of Sugar Consumed 2/3 kg
Step 2
What is to be found out?
Qty of sugar left  (in kg)
If it was asked in Grams then you will have to convert the kg into grams ie. 1 kg= 1000 grams
Step  3
What is to be done?
Add Qty One + Qty 2
Then subtract 2/3 kg from the total
What is left is the answer to the problem.
Step-4
Formula
Qty 1 + Qty 2 = Qty 3
Qty3 x 2/3 = Total sugar consumed.
Step 5
Working
¾ + ½ = ( LMC 4)
(3+2) / 4 = 5/4 kg
i.e 5/4 – 2/3 = LCM of Denominator 3 and 4 = 12



{(5x3) – (2x4)}/12 = 7/12 Kg
Step 6
Answer
Hence the qty of sugar left would be 7/12 kg




Check
5/4 – 7/12 = ?
(15-8)/ 12 = 7/12 kg. Hence the answer is correct.

How to remember the formula?
There is no short cut- one has to write, Re-write and remember. Practice as many sums as possible in that particular chapter.
Remember Derivatives of the same formulae
Is Speed x Time = Distance, Distance/ Speed = Time or Distance/ Time= Speed.
Practicing Vedic Mathematics helps in improving speed
For Smaller Classes:
Read- Write and Memorize tables up to 20 x 20
Square Roots and Cube Roots up to 100
Arithmetical formulas to be written and memorized
Daily work out a  in of 20 different sums.
Take help of internet and practice speed maths
Do your class work without fail.
Be neat and draw figures wherever necessary.
Geometry: To do well in this one must understand the CONCEPT
Practice by drawing and reasoning and logical approach to theorem

Revision of all the chapters taught once in a Fortnight would be a big help to recall and refresh your mind. Once again you must practice by working out various samples.
Go in for Model papers and previous years Question papers.
This method helps you in two ways.
a) Speed and knowledge of the pattern of questions asked in the exam
b) Check with the given syllabus and complete the chapters before you move in for mock tests.
c) ONLINE TESTS would be of immense help to those who are preparing for Entrance Examination/ Competitive Exams.
d) Group study, this depends upon the individual, this will help only to clear doubts. Beware this will waste a lot of fruitful time and concentration goes for a six.
e) Just 60 days before the exam you should start revising and one month before the exam start Practicing with model tests Time based tests would be best.
Stay ahead of others in the class
This is done by preparing for the chapter yet to be taken.
Go through the chapter that is about to be taught in the class and note down the doubts if any, This will
