Exam Stress

Stress is natural part of being human. It's your body responding to changes in the world around you. It changes how your body works and puts your mind into different moods. When you're getting stressed about an exam - it just means that you really care about the result you will get. That can be a good thing if it pushes you into working extra hard as you try to get a good result. But it can be bad if you get too worried and the effects of the stress stop you doing well. When exams get too much, the stress can show in your body.

How to spot if you're stressed

You could be showing signs of stress if you're:

• feeling tired

• ache all over

• cry and feel sad

• have panic attacks

• have broken sleep

• suffer from stomach upsets

• have itchy skin rashes

• more likely to get colds and 'flu

Developing a positive mindset

Its human nature to be negative sometimes, but developing a positive mental attitude will help you do your best.

• Picture yourself getting a big fat A and visualize this over and over in vivid detail. If you maintain a positive, 'I can do it' attitude building up to your exams, your stress will be transformed into positive energy that can be harnessed to enhance your performance.

• View the exam as a time-bound project of 90 days. Look forward to the fun and challenge in store on completion.

• It’s only an exam! You’re not going to die. Your family will not get kidnapped and tortured if you fail. And there’s always the resit!

• An exam is simply an opportunity to show what you know.

• Exams are designed to HELP you, and provide your tutors/teachers with feedback so they can help you further.

• You will be just the same person before and after the exam. Exams don’t measure anything really important about you.

• You have had a number of successes already and have actually passed many exams - hold on to that. Focus on the positive aspects of the past rather than the negative ones, as this will spur you on to yet more successes.

Stopping negative thoughts

Thought-stopping technique

When we become anxious we begin to have negative thoughts ('I can't answer anything', 'I'm going to panic' etc). If this is happening, halt the spiraling thoughts by mentally shouting 'STOP!'. Or picture a road STOP sign, or traffic lights on red. Once you have literally stopped the thoughts, you can continue planning, or practice a relaxation technique.

Use a mantra

Derived from meditation, a mantra is a word or phrase which you repeat to yourself. Saying something like 'Aum' or 'relax' under your breath or in your head, over and over again can help defuse anxiety.

Focus

Looking out of the window, noticing the number of people with red hair, counting the number of desks in each row... all help to distract your attention from anxious thoughts and keep your mind busy. Mental games such as making words out of another word or title, using alphabetical lists etc are all good forms of distraction.

Bridging objects

It can help to carry or wear something with positive associations with another person or place. Touching this bridging object can be comforting in its own right, then allow yourself a few minutes to think about the person or situation which makes you feel good. This can have a really calming effect.

Self-talk

In exam anxiety or panic we often give ourselves negative messages, 'I can't do this' 'I'm going to fail' 'I'm useless'. Try to consciously replace these with positive, encouraging thoughts: 'This is just anxiety, it can't harm me', 'Relax, concentrate, it's going to be OK', 'I'm getting there, nearly over'.

More  tips

A good way to minimize the amount of stress that you are feeling is to create a revision timetable. This way you can be make sure that you have plenty of time to revise all the subjects that you need to do. Having a revision timetable will also give you the chance to build in rest breaks and time to spend relaxing. This will help you to stay calmer. If you find yourself sitting and getting more and more stressed you need to take a break. Go for a walk or take an hour to watch some television do something to take your mind off your stress.

TIPS FOR STUDENTS AND MBA ASPIRANTS TO IMPROVE COMMUNICATION

MBA Aspirant needs to master his communication skills to perform exceptionally well in MBA from a reputed Business school and prove his mettle while studying as well as in the corporate world. He should definitely have an edge over the other candidates, if he has excellent and impressive communication skills.

Let us go through some handy tips to improve the communication skills:

Read a lot. Reading is the key to an effective communication. Pick up any magazine, journal, novel or for that matter the daily newspaper and do make it a habit to read it aloud. It has generally been observed that when an individual speaks, he falls short of words. The words are somewhere hidden in his brain and refuse to come out. When you read aloud, after sometime, words automatically fall into your mouth and thus improve the communication skills. If you come across any new word, do check out its meaning and try to add it in your speech the next time you speak. Reading also enhances your general knowledge and makes you aware of what is happening around you. Read anything which interests you.

• One can gain a lot while watching Television. If you are watching any talk show or interview of any great personality don’t just stare at the pictures, try to follow the way participants interact with each other, carefully observe their accent and also learn new words from them. It is okay to watch movies sometimes but not always, an MBA Aspirant must watch some educative channels to improve their general knowledge as well as communication skills. 
• Remember there is no end to learning. An individual can learn new things at any age. While interacting with anyone, if you come across any unknown word, do not feel shy or hesitate to find out its meaning. No one will make fun of you, instead would appreciate you for your initiative to learn more.
• A child has to first learn alphabets to be able to make new words. In the same way, for an effective communication one should be very clear with the basic concepts of communication. Learn tenses, homophones, homographs, hetero graphs, vowels, consonants, verbs, phonetics as they are the stepping stones to an effective communication. Ignoring the above things will never let you communicate correctly and effectively. Always adopt a step by step approach.
• Be patient. Don’t be in a hurry to hone your communication skills in a day or so. There is no medicine or any magic stick which can improve your communication skills in a day. You have to be patient and give yourself time. Never feel dejected if others speak better English than you, instead learn from them and seek their guidance. It is rightly said” Practice makes a man perfect”. Practice a lot. Whatever language you want to master on, try to interact in the same language with your friends and family for the perfect flow of words. Never feel embarrassed if you are wrong, learn from your mistakes. Stand in front of the mirror and speak to yourself. Ask yourself questions and answer them. Be your own critic. It works.
• One has to be very confident and must adopt the right attitude. Nothing is possible if you don’t have the right approach and attitude. Motivate yourself to communicate effectively. Whenever you learn a new word, treat yourself with a chocolate.
• Your thoughts ought to be very clear for an effective communication. Haphazard and unorganized thoughts lead to an ineffective communication. Be very clear what you intend to communicate. Don’t just speak for the sake of speaking. Carefully select sensible and relevant words to put your thoughts into content to be shared with others. Don’t keep half of your words in mouth, speak properly and clearly. You yourself have to be very clear with your thoughts for others to understand it well. Design your content by keeping the audiences in mind and don’t make it complicated. Keep it simple.
• Be a patient listener. An individual cannot be a good communicator, unless and until he is a good listener. Never interrupt any speaker in between The other individual might not be as learned as you, but you should always respect his opinions. Even if the other person is wrong, don’t criticize him; instead wait for your turn to speak. Always listen to the other side of the story and then only give your expert comments.
• An MBA student throughout his two years of academics has to do exceptionally well in presentations and seminars. You just can’t escape them. One has to be a very good speaker to fair well in presentations and stand apart from the crowd. Never ever panic and do create a friendly ambience while delivering a presentation. One has to understand the importance of non verbal communication as well. Keep a control on your hands and emotions while speaking. Don’t play with your pen or handkerchief and never smile unnecessarily. Don’t start sweating in between presentations. The audience will never bite you, so please do make an eye contact with them. Do not forget to greet them well with a warm smile.

MBA doesn’t only mean learning the four P’s of marketing or cramming Philip Kilter. It’s much more than that. One needs to be an extrovert and must know how to brand oneself. You must know how to position yourself in the market place and impress others. Be very careful about your pitch and tone. Never murmur while speaking. Don’t speak too slowly or never be in a hurry to speak. Speak loudly and clearly so that you are audible to one and all. No one will notice you if your tone and pitch is not clear and you will be lost in the crowd.

One might be good in academics, might be very intelligent, but to carve a niche in today’s competitive world, one has to be an exceptionally good communicator. Impressive communication skills coupled with your MBA will definitely take you to the pinnacle of success. Always remember confidence, clarity in thoughts, practice, good listening as well as reading skills are the main ingredients of good communication skills. One has to take good care of all the above to emerge as a winner and rule the world.

Measuring File Size of YouTube Video

The "Normal Quality (NQ)" YouTube encoding is around 300Kb/s combined for audio and video. So if the video is 10 mins long , you can figure out that the file size will be around 22MB or so.

Here's how you do it.
First calculate the length in secs. A 10 min video is 600 seconds.

Mulitply that by the bitrate in Kilobits per second (300 in the case of NQ).
600x300= 180000

Next divide the result by 8 to convert it to KiloBytes
180000 / 8= 22500

Divide that result by 1024 (how many KiloBytes are in a MegaByte)
22500 / 1024 = 21.97

~22MB

Obvisously the High Definition (HD) and High Quality (HQ) encodings are encoded at much higher bitrates (~2000Kb/s and ~600Kb/s respectively).


Now
The "high quality (HQ!)" YouTube encoding is around 600Kb/s combined for audio and video. So if the video is 10 mins long , you can figure out that the file size will be around 44MB or so.

Mulitply that by the bitrate in Kilobits per second (e.g. 600Kb/s in the case of HQ).
600x600= 360000

Next divide the result by 8 to convert it to KiloBytes
360000 / 8= 45000

Divide that result by 1024 (how many KiloBytes are in a MegaByte)
45000 / 1024 = 43.94

~44MB
