[O/A-Levels Tuitionś]

If you want to learn from the comfort of your own home, I am available to teach IGCSE/Olevels subjects online via Skype ...

Subjects :
Biology
Chemistry
Physics
Mathematics
English
Urdu
Pakistan studies
Economics

I've got lots of helpful resources and study tips to help you ace your IGCSE exams. My working hours are also quite flexible.

Did you know the best way to learn is by having a student teach you? That's because they can understand you better because they had the same exact confusions once. That's why group studying works so well!

If you'd like more information, feel free to contact me.

Since 55% were fluent in xhosa(and zulu since this figure is not for xhosa "only" but xhosa and zulu both ) 45% will be fluent in zulu only(100-55). 45% of 60=27. 27 is the no. of male applicants that were fluent in zulu only

Somebody please tell me a way to study math olevel without tuitions

Refer to D series (D1,D2,D3,D4) and syllabus. Do all exercises of D series of topics that are in syllabus and there are really great notes of "all" chapters in the series if u read page after page. Then do topic wise pastpapers and finally unsolved yearly ones.

Is it possible to finish maths (with past papers) in 2 months without any tution or schooling??

That depends you how much time you allocate towards maths only per day, If you study for significant hours then you might be able to finish the syllabus, but you ll have to make some really good notes and everything else really fast and actively practicing everyday but it is possible without tuition and school only if u r good at basic maths.

I second with Romeo Sheikh . I solved the past papers of last 7 years almost twice before exams; once in April, and then for second time before my papers, as I had 4 holidays . All what matters is determination and effort! And completion of syllabus in one month is very simple. Take a copy of syllabus, and mark the topics which you don't know. Then study those topics from the D-series (they are the best), and straight away head for topical questions. If you do one or half topic per day, you'll be good to go!

Re: O'level Maths, Addmaths and Statistics help available he

Thank you hamidali391 for creating such a thread. Here's my question: In Oct/Nov 2006 paper 2 (maths 4024:http://www.xtremepapers.me/CIE/Cambridge O Levels/4024 - Mathematics/4024_w06_qp_2.pdf ), my answer to the last part of the last question comes as 10/447 whereas the er (http://www.xtremepapers.me/CIE/Cambridg ... w06_er.pdf ) states it as 10/449. Anyone please look into this matter!
Secondly, when asked to find values using a graph, are dotted guide lines necessary or can we simply write our answers directly?
Thanks.

Dotted Lines are Neccessary

q: 19:

a= |10| - |-16|
a = 10 -16
a = -6
putting this value of a in the second one,

b = | (a-6) | - | 20 |
= |-6-6| - |20|
= |-12| - |20|
= 12 -20
= -8 (Ans.)

CD = 10 units
AB = 3 - (t)
10=3 - t
t = -7
ans is C

thanks!
can you also tell me how do we find magnitude of a line on graph? like whats the formula.. I have forgotten it all
and can u try to solve the very first question I posted too, please

 

[Rizwan Javed]

You can use the formula:
magnitude of a line = ((x2-x1)^2 + (y2-y1)^2)^0.5

But if the line is horizontal, minus the larger x coordinate from the smaller one.
and if the line is vertical, minus the larger y coordinate from the smaller one.
^ In these cases, there is no need to use the formula.
