You have to study:
1-Viruses, Bacteria, Fungi, Flowering Plants, Arthropods
2-Practical work
3-Eye
4-Food Test
5-Characteristics of living organism
6-Classification of living organism
7-Cell structure and organization
8-Magnification
You forgot to say enzymes, osmosis, diffusion, germination, transpiration, translocation haha :p
When i was doing a past paper today i saw a question that said draw the xylem and phloem arrangement in a root and stem.. learn that too!
Remember.. Xylem is inside and phloem outside..

Minimizing heating effect of a current:
• Lower current
• Increase voltage
• Add a lamp
• Increase resistance of a resistor

To increase accuracy of ray diagrams
• View bases of pins since pins may not be vertical
• Keep pins further apart
• Use more pins
• Avoid parallax, explain action and reason
• Repeats and average

Adjustments made to experiments will be made to increase accuracy

Improvement made to experiments about heating effect and insulation
• Lids
• Repeats
• Stirring
• Record max. Temperature
• Add insulation
• Keep constant room temperature
• Avoid heat loss

How to check if a rule is vertical:
• Protractor
• Use of set square
• Plumb line
• Spirit Level

Precautions taken in experiments about formation of images by a lens
• Use a darkened area
• Meter ruler on bench or clamped
• Object and lens same height on bench
• Mark on lens holder to show center of lens
• Take more readings
• Avoid parallax error, explain action and reason
• Lens\screen perpendicular to bench

Variables in experiments about springs and stretching effect:
• Number of coils
• Length of spring
• Diameter\thickness of spring or wire
• Range of loads
• Length of wire
• Coil spring

Periodic time (T) is measured by timing a number (n) of oscillations, then divide the time taken for all the oscillations by the number of oscillations (n)

Drawing graphs:
• Label axis
• Choose a proper scale
• Well judged best fit line
• Thin and neat lines

Measuring the gradient:
• Draw a triangle on graph
• Use clear lines
• Triangle must be larger than half the line

Sources of error in calculating circumference by string method:
• Parallax
• Diagonal winding
• Thickness of string

Improvement made to calculating circumference by string method
• Avoid parallax error
• Repeats and average
• Thinner string
• Parallel winding of springs

It's not the BEST list in the world, but hopefully it will help... :wink:
Best of luck, Inshallah we'll all get A* :D

Hey
I gave my math 0607 (extended) a few days back...the pattern was quite different. Does anyone know about any changes CIE has made for any of the other subjects? As in, are they changing the pattern for this years May/June exams? - India, zone 4.
