How to get Marks in Math Ecat 2016

Tips regarding ‪#‎Maths‬ subject

As in our page Maths subject is almost out of our consideration
So today I want to talk about it
If you want score highly in Mathematics. First of ALL Do learn and cover All the Formulas of each and every chapter with finger tips which is very easy if you try. When you get grasp on all 1st and 2nd books formulas for sure your round about 25MCQz are confirmed. I mean in such MCQz they only ask you to direct them towards the Right formula thus you WILL Not be needed to solve or use it further but just a Pure formula is required. Repetition is important in maths. You learn how to solve problems by doing them so keep on practice problems but don't do it blindly. Make sure you learn how to recognize when/Why you should use a specific method to solve a problem. If you see few Maths MCQz may take long time and chances are many that you won't be reached to the right answer but don't be panic leave such questions for 2 go but don't cross the work rough work Even if you know the final answer is wrong,
don't erase your entire work because you may
get partial credit for using the correct
procedure. So when you passed through all the others MCQz and come back to the unattended question you will come to know that the same question will be solved very easily by you.
So that's Normal in Maths in such MCQz takes seconds while others takes minutes so in average whole maths portion can be solved in the given time very smoothly and if you have this thing you into your mind you will confront the lengthy MCQz with ease face and you won't feel the need to be panic. Another important thing is that I think for maths students Pencil in hand is very crucial just jot down the answer and solve the problem in front of each and every MCQz though they will forbide you to write in the question sheet but don't listen them nothing will be happened if you go to the last sheet for the solving problem it itself is an another problem.
Last tip I Would Request all maths candidates that kindly solved all books examples of 3-6steps questions because most probably they give the books examples I have observed this thing so Many times
And remember these types are solely for Maths students but others may take advantage of these too
In short Maths subject is the easiest in ALL <3
I LOVE IT TOO MUCH

How To study For Exams

Top 10 Study Tips


Exams are an inevitable part of student life, but they don't have to be a painful one. The skills and tips in this article can help you get through your exams. They can also help prepare for tests, presentations and other in-class assignments.
Here are our top ten tips for preparing for exams and getting through them on the day.
> 1. Find out about the exam
> 2 Ask For help
> 3 Sort Out your subject Material
>4 check past exam paper
> 5 know where to Go
> Dont cram
> 7 Keep yourself Cool
> 8 use your reading Time
> 9 break the questions
> 10 review your skills
11 make own stratiges

 1 Find out ABout Exams

 Know your enemy - find out as much as you can about the exam.

• How much is the exam worth to your overall mark in the subject?
• What type of exam is it? Is it a multiple choice, essay, open-book or take-home exam?
• Will there be a choice of questions or tasks?
• How much will each question or task be worth?

2 aSK for help
 Don’t feel bad if you need to ask for help. Talk to your teacher or lecturer and pick the brains of other students. If you’re feeling really stressed you might also find it helpful to speak to a counsellor

3. Sort Out Your Subject Material

Check that you have all the relevant handouts and get all your notes together from the subject. Read through the course outline or subject guide (if there is one) and use it to organise the information you’ve collected.
It might help to write your own summaries of each textbook chapter or section of the subject guide. This will make it easier to find what you need while you’re studying.

4. Check Past Exam Papers

Get your hands on any old exam papers from the subject and familiarise yourself with the structure and format. Your teacher or lecturer should be able to let you know where you can get your hands on some. Your school or university library might have past exams on file, too.
Practise answering the questions within the specified time limits and check your answers against your notes to make sure you’ve got them right.

5. Know Where to Go

Check your exam timetable for details on when and where you’ll be sitting the exam. Make sure you have everything you’ll need to take with you (e.g. calculator, pencil, ruler, etc).
Try to do some study at the times your exams will be on. If you have an early morning exam it’s a good idea to practise getting up and doing some study earlier in the day.

6. Don’t Cram

Stick to what you already know when studying the night before an exam. You’ll only make yourself nervous if you try to learn new information. Review your notes or test yourself on key points.

7. Keep Your Cool

Don’t talk to other students about the exam before the exam. It could confuse you or make you lose confidence in yourself.
The same goes for after the exam. Don’t hang around talking about what was on it or you’ll start to doubt yourself and stress out if you think you made a mistake.....

8. Use Your Reading Time

The way you use your reading time could make or break you in the exam. Use it to plan your writing time and start thinking about some answers.
Read the instructions very carefully then scan the whole exam paper. Be sure to check how many pages there are and how much each question is worth.
Plan how much time to spend on each answer and the order in which you’ll answer them. Start with the questions you’re most confident with.

9. Break the Questions Down

A great tip for any exam is to break the questions down to make sure you really understand what you’re being asked. If you don’t answer the question properly you won’t get full marks for it.
Look for the key parts in the question and these will give you clues on how to answer it. For example, for the question, "Explain the difference between study and revision", you can split this question into four parts:

1. Explain - give reasons to show how or why something is the way it is
2. The difference - what are the distinguishing factors between study and revision?
3. Study - what is study?
4. Revision- what is revision?
5. revise again and again   

Come Up with Your Own Strategies

Remember - these tips are only some of the things that you can do to get the most out of your exams. There might be other things that work even better for you.

Ask around - find out what your friends do for their exams - maybe some of their tricks will work for you too! Maybe your teachers have some good recommendations too.

Whatever it is, whatever strategy when you find something that works for you, put it into practise and good luck!
