Can anyone help me with percentages re sons report?

[charlize]

I must be dum cause iam finding this hard to work out.
My ds who's 11 just got his report. He sat 2 english tests. One had 2 sections,A and B. And the other was story writing.
The one with two sections,Section a was worth 25 marks and section b 10 marks. My son left out section b. He ran out of time even though section b would have only taken him 5 mins as it was a passage with missing words thingy.
The other test which was a story to write I don't know how many marks that was worth, Any teachers here??
Any way he ended up with 67% for English on the report. The top mark in class was 82%. Can anyone tell me what his likely percentage would have been if he had gotten another 10 marks from section b??
Iam a bit confused as to how they have converted the marks into percent. Am i right in guessing that the marks available for the story would have been about the same as the marks available for test 1, ie 35?
Or would it have been more or less?
Well that was as clear as mud, can anyone help?? Please.

I think... your son could have had a mark of 77, if he had done section B perfectly, and assuming the story test had equal marks in the final test score as the SEction A-B test...

OK, having just done some maths, deep breath...

The total score for the test was 35 (assuming that there was no weighting of the two parts)

Therefore 1% = score of 0.35

Your son scored a 5 of 67% so that equars a mark of 67x 0.35 which is equal to 23.45

if he scores 10/10 in the second part he would have got 33.45. 33.45/ 0.35 + 93.57%

So he would have come top. Just a word of caution tho, he may have done better on the first part because he ran out of time.....time could have been a factor in the test IYSWIM.

Either way, the boy dun well!

Oh, no, bother, see, I can't work it out, either! I should have said, 77, if he did section B to the same standard as the other work, and 81 if he did section B perfectly. But it all depends on the weighting that the 2 tests have relatively to each other.

Zebra??? Now I'm confused, where did I go wrong???

Lol, My very little brain is hurting with all this maths.
Hmb I would be delighted if it means he would of got 93% but did you put in your calculations that section be was only worth 10 marks wheras section a 25.
Iam ust guessing that the other test the story was worth 35 marks like test 1. that would make a total of 70 marks for the whole thing. which they could then convert into a percentage.
Dam it I haven't got a clue have I.
Zebra I would also be delighted with 77, which is what i thought it might be if i simply added 10 marks he missed out on top of the 67 , but then i remembered it had been converterd to percent. Ahhhhhhhhhh!!

Ah, sorry I didn't spot that the test had the second part. I think that my maths were correct if the whole test was out of 35 only.

If you are assuming that the other part of the test made up the marks to 100, then the calculations are easier. he scored 67% without any marks from the 10 mark question. So with an added 10 marks that brings his marks up to 77%

Assuming that he scored 67 out of 90 (because he missed the 10 mark question), his performance adjusted percentage (ie assuming that he does as well in the missing bit as the rest if the task) would be 74.4%

There is no way of knowing, from the percentages how much the second part of the test was worth.

If the second part of the test was worth 35 then a score of 70 would be 100%. So 1% = 0.7 of a mark. If your son had a percentage of 67% this means that he scored 67 x 0.7 = 46.9, round it up to 47. If you add on 10 he would have got 57 which is a percentage of 81.4.

If you just carry our the percentage of the parts he sat (which would be an adjusted score) he would have scored 47/ 60 = 78%.

I hope you realise that I have housework to do !!!

Ahh! hmb well done. I see what you mean, that all makes sense now. Yes 70 would prob have been 100% therefore 10 marks would be 14% of this??
So if he had gotten 10 marks he would have got 67 plus 14 % which is 81% but if he had gotten a few wrong which is more likey he would have gotten 77%.
Thanks, Hmb and Zebra. Maths was never my strong point. Come to think of it neither was englics oopps

That's how I figured it, but I couldn't explain it very well! I guess we've all done that on tests; I hope it doesn't affect him too much.

Although, iam now thinking that the second test ie the story was only worth 25 marks. Because I have just been informed by ds that he was given 50 mins to do test 1 and 40 mins to do test 2.
Section b of test 1 what he missed out is expected to take 10 mins and is worth 10 marks.
So therefore cos test 2 has 10 less mins on it and no section b iam inclined to think that it is worth 25 marks and not 35 like test 1.
This would make 100% 60 marks and 10 marks 17%
which would mean, if he had gotten all of section b right he would have 67 plus 17% which is 83. But more likely he got a few wrong.

Red green stripes. It won't effect him now cos it was a mock entrance exam. He has the real one in Jan, so at least now we know he has to work on his timings, better for this to happen now than in the real exam.
