by Tim

  1. Know your text(s)

  • Have a thorough understanding to the main themes and concepts within your texts of study
  • A way to test your knowledge is to write a paragraph in your own words explaining and describing your insight to a particular theme in your text.
  1. Put all your notes into a table

    This will organise your notes neatly and allow you to easy access your notes.

  2. Draft 1… Draft 2… Draft 3…

  • Whether your assessment task is an essay, creative task or speech you should have your first draft (typed or written) at least 2 weeks before your exam.
  • Write about themes that your liked or enjoyed when you were studying the text. Expect to make multiple drafts for your assessment tasks, especially for creative writing.
  1. Hand in your Drafts to your school teacher, tutor or parent/friend to read and edit

  • Remember to get comments and feedback from the person who read your Draft.
  • Make the appropriate changes according to your Drafts to make it even better.
  1. Read other essays/creatives and become the person to give feedback

  • Read other people’s essays/creatives to gain insight only and not to copy them
  • Read to learn from them, look at their strengths and weaknesses, and see how you can replicate it in your own way.
  • When reading, out yourself in the shoes of an HSC English Marker. This way you will understand what are the specifics that they are looking for and repeat this step with your essay/creative.
  1. Practice… Practice… Practice…

  • Practise answering different essay questions with your ‘perfect essay’ and practise moulding your response so that you answer the essay question each time.
  1. Never memorise responses, only memorise your main ideas and analysis

  • During the exam you must be writing your response to answer the question or stimulus given.

Maths Puzzles

The Missing Dollar Problem

Three friends eat lunch at a restaurant, and the bill comes to $30. They each pay $10. While leaving the table, the waiter realises that the bill was incorrectly calculated, and actually came to a total of $25. Knowing that $5 cannot be divided into 3 evenly, he pockets $2 himself and gives the friends $1 each back.

So, each friend has paid $9, and the waiter has pocketed $2. But $9 + $9 + $9 + $2 = $29. Where did the missing dollar go??

Solution: There really isn’t anything missing – just a play on words. Accounting rules need to apply. Click here for a more detailed explanation.

Who would you hire?

Imagine you’re the employer of a big company, and you need to hire someone for one month. There are two top applicants. Applicant A wants to be paid $1000 per day ($30,000 over the month). Applicant B wants to be paid 1 cent on the first day, 2 cents on the second day, 4 cents on the third day, 8 cents on the fourth day and so on, doubling each day until the month is over. Who would you hire?

Hint: You can calculate how much Applicant B wants to be paid on any given day by using powers of 2. For example, on day 4 he wants to be paid 2^3 = 8 cents. On day 10 that’s 2^9 = 512 cents.

Solution: Applicant B would be paid more than $10 million over the month! He would be paid $5,368,709.12 on the 30th day alone! (Calculated by finding 2^29). This question shows just how big the powers of a number can quickly become!

Probability Pandemonium

Crazy Kids:

Imagine that you know a family has 2 children (that aren’t twins). Later, you discover that one of the children is a girl, what then is the probability that the other one is a girl?

Hint: it’s not 1/2!

Answer see below…


Devious Doors:

There was a games show which included a section in which you could win a car by correctly selecting which door it was behind. It went like this:

  1. The host would ask you to pick and stand in front of 1 out of 3 closed doors, 1 of which had a car behind it, the other 2 with nothing
  2. The host would then reveal a door that you hadn’t chosen that had nothing behind it, leaving two unopened doors, one of which you were still standing in front of.
  3. The host would then ask, would you like to stick with the door you’re currently with, or would you like to switch to the other remaining unopened door?

If you wish to maximise your probability of winning the car, what should you do?

Answer see below…



Solution Crazy Kids:

You have to consider the possible combinations of the children’s genders and how the information came to you.

When you knew that they had 2 children there were 4 possibilities:

Older:                   Boy        Boy        Girl         Girl

Younger:              Boy        Girl         Boy        Girl

When you discover that one is a girl it eliminates the possibility that they’re both boys, it also leaves only 1 of the remaining 3 that has the second child as a girl.

Therefore the answer is 1/3!

Solution Devious Doors:

You should switch!

When you first chose your door there was a 2/3 chance that it contained nothing. Despite the host eliminating one of the nothing outcomes it is still more likely that you are currently standing in front of a nothing outcome because of when you made your selection.

Therefore since it’s more likely that you have nothing and the other nothing option is gone you have a 2/3 chance of winning if you switch to the remaining door! Deal or No Deal works on the same concept to a much larger scale.
