Thx a lot dude, but had these already...xD
But still thx and you will do great in exams InshAllah

Hello guys.....I ma also giving Chem and Phy unit 3 this year....
What kind of experiment related to waves come, or may come in the detail experiment question of abt 11 marks..Any idea?!?!?!?

The experiment about measuring refractive index of glass might come.

ohhh... well if i'll more i'll send . n yea InshaALLAH. thanks.

Anyone got notes for chemistry unit 6 and physics unit 6?

 

[Ch.Walid]

Any doubts in Physics paper 3?

Any doubts in Physics paper 3?

When asked abt choice of apparatus in volmeter and ammeter, wht are we supposed to write....Wht r there precison?!?!

Well, it depends on the situation. If you want to measure current then you should use ammeter. But if you want to measure P.d across anything like bulb, any component etc. then you should use Voltmeter. I hope this answers your question.

Thx a lot, but wht about their precision??

hmmm...

in this doc u'll find everything about accuracy, precision, errors, etc. If you couldn't then let me know .

Thanx a lot

Its ok.

Precision of instruments
 mm scale (e.g: ruler or measuring tape) 0.50 mm
 Vernier 0.10 mm
 Micrometer 0.01 mm
 Stopwatch 0.01s  reaction time in stopping and starting stopwatch
 Angles 0.5º

Improving accuracy
 Repeating readings and calculating average
 Taking reading at eye level to avoid parallax error
 Hold apparatus vertically
 Release from rest (If it involves releasing something)
 Check for zero error
 Exclude anomalous values

Aisha Abdul Quddus Hope this helps.

Answer of June 2012 unit 3 paper qs no. 8(b)

See, dude, a couple of years ago, The mods themselves would block the forums so no one could gain an unfair advantage, but please realize this:
IAL and the reserve (R) papers were created so that the problem of timing could be solved. People in different time zones have different papers, and so, all IAL papers end together, all R papers end together and all GCE papers together. This is also the reason students no longer have key time. So, please stop putting unncessary bans on our discussions

So, lets discus papers !

CIE candidate and i dnt take physics or maths

 

[dubi2pro]

how did you critize the results?

Ohh, sorry lol.

How many of you guys are ready for the Edexcel IAL unit 6 chem and bio on 15th and 13th respectively?

I'm preparing for IAL Physics Unit 6 and IAL Unit 6 for chemistry.

btw hows your preparation for IAL Unit 6 chemistry?

oh its going good mate.. shouldn't be too hard.. have u done jan15 unti6 for chem? how did you find it?
