Regarding Physics P4

Do they have a process of ecf in physics paper 4?

If a part has a relation to the previous part and we use previous part's wrong answer in the next one but with correct procedure, do we get full marks?

Yes, you will receive ecf. However, don't worry. The thing is your results are not actually compared with the supervisor's results. It is your results that they will take into consideration. But your results should be reliable. For example, if they ask you to calculate the final 'g' value, as they did in paper 33 this year, a suitable range for the 'g' value will be from 1.0 ms-2 to 30 ms-2, from your results. However, more than this value,, your results might not be reliable and is therefore regarded as incorrect readings. For an example if you get 100ms-1 , your results are wrong. Hence marks are deducted for your readings. However, ecf is given from (b) onwards. But if your graph is incorrect, you will loose graph marks too. If your graph marks is incorrect as well, most probably, you wont get marks any further cos :( you will make the examiner pissed off surely and he'll scribble on ur paper. But that is not so according to CIE systems. Each candidate is marked accurately it seems so you cannot deduct like that. Hence, you will receive ecf from part (c) onwards.

Oh sorry. I thought of paper 3. Well paper 4, this is how it works. Paper 4 :
Since first, mostly, they will ask about the definition there is no ecf for those. But, ecf is there for some explanations and calculations
CALCULATIONS
If they first give to calculate something and you got it wrong you are not awarded marks for that question. However, if your answer that u got wrong is required in the next question, you will be given ecf. Also, if they mention 'using your answer to part 1' etc, you will be awarded ecf.
EXPLANATIONS
i
t is very hard to get an ECF in explanations. However, there are some questions. For an example,
1 (a) Explain what will happen to the wave at point P? (2 marks)
(b) (i) Explain what will happen to the wave you described in (a) if
1. Intensity is decreased
2.Frequency is increased (2 marks)

-----------------------------------------------------------------------------------------------------------------
In this question, you will loose 2 marks for (a) but will be given ecf from (b) onwards. This happened in paper 22 May/June 2017.
Thanks. Sorry for earlier!

The thing is this year's Physics paper was legit tough and IF cie doesnt keeps lenient checking+ low gt then we are all losing marks like running water. I bet esp for this year there will be more chances of awarding ecf for paper 4 physics.
