    Tips for Physics, Chemistry, Maths and a studying schedule!

    Re: Tips for Physics, Chemistry, Maths and a studying schedu I'm giving 17 subjects. And my opinion is just as the admin said above. Chill and don't panic. Revise what you forget often. The rest depends on how well you have done in the months that have gone behind. Have confidence in what you...

    Additional Math

    The question already states that take values of x(equal to and greater than) 1. And no, the graph is not at all a necessity. In examination conditions you won't even find that much time. In fact it will be a said waste of time. In this case the range can easily be calculated by using x (is equal...

    help please!

    Outliers are "extreme" values that do not generally fit the trend of the given data. For example, assume a data set: 10,11,12,13,14,15,16,17,74. Did you notice the outlier? Yes, its 74. Assume further that the question asked you to calculate the median. As the data is already arranged in...

    Advice for Urdu, Islamiat and Pak. Studies CIE?

    I assume you're talking about Urdu second language. Answers for comprehension must be in context which means use your own words and do not copy paste from the passage. With the exception of 1 or 2 marks qsts that would probably need a copy paste. Follow the word limit in the summary question and...

    what does A* stands for

    A* Will be set as much above the A grade as much as the score required for grade B is below that required for grade A. A* will be mapped onto a percentage uniform mark of 90% (though this will never be shown on any certificate) and likewise grade A will be mapped onto a percentage uniform mark...

    Help me in choosing subjects

    If you're interested in Engineering then Biology will not be a good idea. So, drop that out of the list. Secondly, Additional Mathematics is not a subject you should leave if you want to do engineering. Thirdly Statistics is an optional. Many people do it as an extra subject. Its not at all hard...

    Pak.Studies and Islamiyat Notes!

    Quantity cannot make for quality. At least not at all in Cambridge. The first important thing is to focus on command words. Understand the demand of the question. Don't just launch into writing all that you know about a particular topic. For example a question worth 4 marks that says...

    help in physics

    C and D can clearly not be the answers as a metal is a conductor anyways, and the situation already mentions that the metal is hot. The subject of the question is why didn't the hand feel it. So the concept of the metal being a conductor or non conductor is irrelevant. So, we eliminate C and D...
