The best way to prepare for exams is to go through past year examples. You should thoroughly read, discuss solutions, and understand the exercises completely.

For psychoanalytical exams, there are additional points you should consider:

  • Be confident, which should include:
    • Check out the test site before the exam
    • Chose your breaks
      • When they say "go", take a 15 second break. This is because you're so nervous, you start to read, and when you're at the end of the passage, you notice you haven't understood anything!
      • Between each long passage (usually several questions relate to a single passage), have a 15 second break. Do this because if you don't select when to break, your mind will do it automatically
      • After finishing a block of long passage answers, transfer them to the answer sheet. This will prevent incorrect transfer, but also give you a short break.
    • Note the time. When half time is, and you haven't gone through half the paper, speed up
    • Eliminate: Don't focus on finding the right answer, but crossing out the wrong ones. First, cross out the obviously wrong answer. Then cross out the answer which is wrong with a bit of insight. From the final 2, guess the answer that most correctly answers the question, because:
      • It doesn't require additional information not found in the passage.
      • It doesn't have words that are too strong, such as "must", "always", "never", "only", etc
    • Don't skip questions: Questions that look hard may be easy, but questions that look easy may be hard. You don't have the time to skip around.
    • Sit upright, don't lean back whilst taking the exam. Even when reading the passage, sit upright.
    • During the breaks, exercise: wriggle your ankles, close your eyes, stretch muscles
  • Think quickly and clearly, because of the pressure of time, which will leave most candidates an uncomfortable feeling when finished. Keep your mind on the ultimate goal, which is to finish as many questions as possible; not getting stuck on interesting passages, becoming obsessed with answering each question perfectly, or introducing your own ideas
    • Write on the answer sheet. To ensure you move on after reading, feel free to cross out the words as you read them.
    • Move on. If a question is taking you too long, You must move on from important questions with a guess.  Randomly choose one of the answers you haven't cancelled out yet, then circle the question to come back if you have additional time at the end.
    • Read to understand the main idea, like you do in a daily conversation, skipping words you don't understand. The key to doing well is to understanding why the person is saying what they're saying.
    • Don't go back to the passage. After reading a passage (to understand it), don't go back to it. The right answer is usually not there, but you can be sure the wrong answers definitely will. Remember what you find hard, others will also find hard.
  • Stamina, due to length of exam

1.3.1 Sum of angles http://projectshum.org/maths/year-8/1-geometry/6-2-angles/1-3-1-sum-of-angles/ http://projectshum.org/maths/year-8/1-geometry/6-2-angles/1-3-1-sum-of-angles/#comments Sun, 17 Jul 2011 14:53:17 +0000 http://projectshum.org/?page_id=1158 Sum of angles

The sum of angles in a triangle is always 180 degrees.

Since we know that the angles of the triangle add up to 180 degrees, we can work out what x is:

90\textdegree+49\textdegree+x=180\textdegree
\therefore x=180\textdegree-90\textdegree-49\textdegree
\therefore x=41\textdegree

"So angles in a triangle always add up to 180 degrees?" Miley asked.

"Yep," Jeremy responded.

"Always???" Miley wanted to confirm.

"Always," Jeremy said, "just like your never-ending love of me <3"

1.3.2 Exterior angle http://projectshum.org/maths/year-8/1-geometry/6-2-angles/1-3-2-exterior-angle/ http://projectshum.org/maths/year-8/1-geometry/6-2-angles/1-3-2-exterior-angle/#comments Sun, 17 Jul 2011 14:52:55 +0000 http://projectshum.org/?page_id=1157 Exterior angle

Exterior angles can be calculated with the knowledge that angles on a line add up to 180 degrees.

Since we know that angles in a triangle add up to 180 degrees, we can calculate x as:

40\textdegree+56\textdegree+x=180\textdegree
\therefore x=180\textdegree-56\textdegree-40\textdegree
\therefore x=84\textdegree

84\textdegree+x=180\textdegree
\therefore x=180\textdegree-84\textdegree
\therefore x=96\textdegree

More complex examples

90\textdegree+x=120\textdegree (exterior angle of a triangle)
\therefore x=120\textdegree-90\textdegree
\therefore x=30\textdegree

Another example:

90\textdegree+38\textdegree+x=180\textdegree (angles of a triangle)
\therefore x=180\textdegree-90\textdegree-38\textdegree
\therefore x=90\textdegree-38\textdegree
\therefore x=52\textdegree

Another example:

144\textdegree=x+2x
\therefore 144\textdegree=3x
\therefore x=48\textdegree

Another example:

x=x/2+47\textdegree
\therefore x*x=2+47\textdegree
\therefore x^2=\sqrt(49\textdegree)
\therefore x=7\textdegree

1.2.3 Equilateral, isosceles and scalene http://projectshum.org/maths/year-8/1-geometry/6-triangles/1-2-3-equilateral-isosceles-and-scalene/ http://projectshum.org/maths/year-8/1-geometry/6-triangles/1-2-3-equilateral-isosceles-and-scalene/#comments Sun, 17 Jul 2011 14:38:08 +0000 http://projectshum.org/?page_id=1156 Introduction

A triangle with 3 sides that are equal are called equilateral triangle, symbolized as:


A triangle with 2 sides that are equal are called an isosceles triangle, symbolized as:


"Hey Jeremy, you squished the triangle!" Miley said.

"That's the point," Jeremy replied, "2 sides are still the same, but 1 is not anymore!"

"I still think it was mean  Q(" Miley commented.

A triangle with no sides that are equal are called a scalene triangle, symbolized as:

Triangles with right angles are called right-angled triangles, symbolized as:

Triangles with 3 angles that are acute (below 90 degrees) are called acute triangles, symbolized as:


Triangles with 1 angle that is obtuse (larger than 90 degrees) are called obtuse triangles, symbolized as:

Remember from year 7 the principles of:

In addition, you should be aware of co-interior angles. For example, in the angles:

Examples of co-interior angles are d and f, which add up to 180\textdegree.

6.1 Area of triangles http://projectshum.org/maths/year-8/1-geometry/6-triangles/6-1-area-of-triangles/ http://projectshum.org/maths/year-8/1-geometry/6-triangles/6-1-area-of-triangles/#comments Sun, 17 Jul 2011 13:53:51 +0000 http://projectshum.org/?page_id=1148 Area of a rectangle

Area of a rectangle can be calculated by Area=Length*Breadth

For example, for this triangle:

Applying the formula:

Area of a triangle

If the triangle is not a right angle you can still find out the half of the triangle, with the same formula above, Area of triangle = 1/2 * (base * height)

For this triangle, applying the formula, it is:

"There we go ;)," Miley said.
