[beeloooo]

ANY IMPORTANT NOTE IR GUIDE HELP FOR BIOLOGY AND PHYSICS ATP PLZZZ I NEED IT DESPERATELY !! ANY HELP WILL BE APPRECIATED.

 

[multixamza01]

Just go through all the experiments in the books. Apart from that Physics ATP is basically general knowledge. So i would say practice past ATP papers. Same for bio , except that you should know how to calculate magnification.

Notes

 

[sweetiepie]

Biology paper 6 tips
in paper 6 u dont need to study alot compared to paper 3
i suggest u to know the drawing and identify most diagram (eg. xylem, pholum, blood vessel, )
the most hardest diagram is about the vertibrate for me (eg, insecta, myriapod, ..... )
u should also know the test for starch, fat, protein, reducing sugar !!!!! (if u need them post it here)
Starch:
Iodine, observe a colour change from brown to blue-black.

Reducing Sugars:
Cut or grind off a small sample and add it to water to attempt to dissolve it. Then add Benedict's solution and heat using a waterbath. Observe a colour change from blue to brick-red.

Protein:
Cut or grind off a small sample and add it to water to attempt to dissolve it. Add potassium hydroxide and copper sulphate. Observe a colour change from blue to purple.

Fat:
Cut or grind off a small portion. Place in a test tube of ethanol and shake. Add the liquid part of this mixture to a test tube containing water. Observe a cloudy emulsifying change.

magnification formula : magnification=image/actual.

every thing else is about ur concept of the course
and dont forget to learn about the effect, use, and where its produce of auxin

hope that helped
