I don't think that's true. I hope it isn't. These exams don't serve their purpose then.....everyone with the paper will score well but the one's who sincerely work hard won't earn accolades. Not fair. Many knew abt the ICT practical papers too. It's so not fair for the ones who didn't know. I don't like cheating and don't like to see other's doin' it.

Yes cheating in the IG's is seriously unfair and i still dont understand how its possible for it to be leaked..

Its better to use multiples of 2,3,4,5 and 10, 20 but not of 15 or 16 on your axis...Also when drawing the line of your graph you can match your points straight with a ruler instead of a curve..like a straight line from point 1 to point 2 then another line from point 2 to point 3 and onwards

3 and 4  allowed?
ru sure about points with ruler, not a curve?

for the different formats of graphs in paper 6 biology::

(a) Graphs

(i) The independent variable should be plotted on the x-axis (horizontal axis) and the
dependent variable plotted on the y-axis (vertical axis).
(ii) Each axis will be labelled with the physical quantity and the appropriate unit, e.g.
time / s.
(iii) The graph is the whole diagrammatic presentation. It may have one or several
curves plotted on it.
(iv) Curves and lines joining points on the graph should be referred to as 'curves'.
(v) Points on the curve should be clearly marked as crosses (x) or encircled dots ( ).
If a further curve is included, vertical crosses (+) may be used to mark the points.

(b) Pie Charts
These should be drawn with the sectors in rank order, largest first, beginning at 'noon'
and proceeding clockwise. Pie Charts should preferably contain no more than six
sectors.

(c) Bar Charts

These are drawn when one of the variables is not numerical, e.g. percentage of
vitamin C in different fruits. They should be made up of narrow blocks of equal width
that do not touch.

(d) Column Graphs
These are drawn when plotting frequency graphs from discrete data, e.g. frequency of
occurrence of leaves with different numbers of prickles or pods with different numbers
of seeds. They should be made up of narrow blocks of equal width that do not touch.

(e) Histograms
These are drawn when plotting frequency graphs with continuous data, e.g., frequency
of occurrence of leaves of different lengths. The blocks should be drawn in order of
increasing or decreasing magnitude and they should be touching.

like temperature and time taken for starch break down for example;

the time taken depends on the temperature.......as temp increase time decrease......

u know wt i mean......the time will change when the temp change not the opposite.....so the time taken is dependent and the temp is independent

okay.but my teacher said usually we put time taken in x-axis.is it right?

thats the " time " wt i said was the " time taken ".......

the first one is like the volume vs time >> here the time in independent so it is on the x-axis.......because the volume of a certain gas (for e.g) will increase as time passes

but the second one.......the time taken for starch to be broken down by enzymes will depend on the temp......as the temp increase the starch will be broken down in less time

is this right?
if the marks for a curve were out of 1, do u think will i get the one?
and check the other things and tell me if it is right or not?
and if anything is wrong, plz tell me what is wrong, or scan the answer
thank

sorry the size is pretty big of the scan


a doubt
they have mentioned like this in the markscheme..



O orientation of axes;
A both axes labelled + units;
S even scale;
P plotted correctly;
L line of best fit or ruled line point to point;


WHY NOT A CURVE? :@:@:@::@:@:@:

Its what the biology examiners prefer...my teacher went to some cambridge conference and they told her there so its better to have a ruled line as its more accurate than a retrded curve :P

the error made my straight lines is more than human error
our curves cause less errors
