I don't think i will, I may die with the sickness!

yup, hey, um what do you think your marks will be like..??

out of 80, may be 60. it could be more or less, I didn't bother to count my mistakes and deduct marks. do you think I can get an A* with this.
wbu?

i think so, but i dont know about myself

i hope i can get the A*.

I did variant 1, it was really easy but there were some tricky stuff.

 

[samanas]

t said on the front page you are allowed to draw any drawing in pencil so im sure its okay

Of course the drawings should be by with pencil !!!

i hope i can get the A*.

hope we all get a*

hey guyscan i ask you something... for the uses of plastic i wrote 1)flexibale
2) it is light / acts as an insulator
is this right?

 

[IGCSE O/L student]

hope we all get a*

yeah!

 

[Lost_Life]

yeah!

I don't know i wrote that it was a poor conductor of heat and that it is light
what did you guys write about the properties of plastic that enables it to be used in electrical cables?

I wrote the same, but I also specified that due to it's light weight it's used in OVERHEAD cables, assuming many cables are fitted underground, and they're more resistant to decay than they are light :x
InshaAllah everybody will get A*. ^^

hey um, i would like to know if what i wrote for plastic and aluminium is correct
For plastic insulation i wrote:

• high melting point
• can be molded to provide maximum insulation

For aluminium i wrote

• low density( aerodynamic)
• resistant to corrosion (oxide layer which makes it suitable for storms )

 

[B333]

the aluminium one is correct but i don't know about the plastic thing

 

[mamoon123]

^What he said, but none of us are examiners here, so who knows, it might be correct. ^^

i guess plastic doesnt have high melting point......

I wrote poor conductor to heat.

yeah , its right..
