#LOL EDITED TITLE IT IS PAPER 6 NOT 3 xD

ALL EXAM WAS LIKE I DOUBTED:
1.Heart and arteries
2.Visible Differences
3.Test of food
4.Germination

WAIT FOR EXPECTATIONS FOR BIOLOGY AND CHEMISTRY PAPER 3 & 1 :) 




Ok...Easy and calm down...Studying for tomorrow's test will be easy ISA

Ok First study the Characteristics of the living organism...most probably he would ask you to draw and tell VISIBLE differences between what you've drawn and another organism...Also be sure to know how to calculate magnification (DUH!!  ???)...NOTE SOMETIMES HE WOULD ASK YOU TO DRAW ACCURATE MAGNIFICATION...FOR EXAMPLE MAGNIFY BY 2 THEN YOU MUST MAKE SURE THAT EVERYTHING IS DOUBLED

Secondly, study reproduction in plant...reproductive organs, seed dispersal and germination..study images for labels

Thirdly, Study Diffusion and Osmosis...90% there would be a question about it

Fourth, Study tropism...it is an often topic in exams  ;)

Fifth, Enzymes...Just know that high temp denatures..low deactivates (can be activated by heating again)...max rate of reaction at optimum temp. (mammals 40 seeds 20-27)

Sixth, TEST OF FOOD....VERY VERY VERY IMPORTANT

Seventh, Labels of heart, lungs, eye, cell, xylem (transports water), phloem (transolcates  ammino acids and sucrose), nerve cells (shapes)...

Last, Any experiment that you got in your study notes SHOULD be studied (most of them are logical ones that you can think about in the exams but be sure to atleast read them)

Now I wish you all good luck and hope we all get an A*...study well  ;D

N.B add rep please for help with upcoming exams/subjects  8)

And don't forget that there will be a graph question...recommended when he asks to compare two results to say positive/negative correlation than direct/inversely propotion

man thats easy anyway,,,,lets say you have drawn an apple its width was 8 cm...the original given picture's width is 2 cm so 8 divide 2 = 4

If he asks you to find original length of image given and there is a magnification given..for example length of image given 4 cm and magnfication given is 400 so 4 divded 400 = 1/100 cm  :)
