I can answer all questions up to, and including, graduate level mathematics. I am more likely to prefer questions beyond the level of calculus. I can answer any questions, from basic elementary number theory like how to prove the first three digits of powers of 2 repeat (they do, with period 100, starting at 8), all the way to advanced mathematics like proving Egorov's theorem or finding phase transitions in random networks.

I can provide good answers to questions dealing in almost all of mathematics especially from A`Level downwards. I can as well help a good deal in Physics with most emphasis directed towards mechanics.

I can answer questions in Algebra, Basic Math, Calculus, Differential Equations, Geometry, Number Theory, and Word Problems. I would not feel comfortable answering questions in Probability and Statistics or Topology because I have not studied these in depth.

All the conceptual questions, pure math & basic stats alike I am good at answering your algebra (including logarithm, functions, trigonometry) and geometry questions. I can also provide to you a firm understanding into basic calculus and other mathematical ideas and concepts. You can either ask questions in English or Chinese. Physics Qns that require rigorous math are also welcomed Important:Please avoid asking me questions related to economics.After all, I am only a secondary school student

I can answer any question in general math, arithetic, discret math, algebra, box problems, geometry, filling a tank with water, trigonometry, precalculus, linear algebra, complex mathematics, probability, statistics, and most of anything else that relates to math. I can also say that I broke 5 minutes for a mile, which is over 12 mph, but is that relevant? 
This does not make sense  a percentage score is a measure of correctness, a rate of correct answers, basically an average or expected number of correct responses out of 100. You can measure the absolute
I believe that, "Romeo and Juliet" is the most heard of play, but I don't know enough about any of them to know which one I would consider as the best. Some other titles that I remember are, "All's Well
Roberta, I'm afraid my previous answer was not quite right (not to mention confusing). Your method of calculating the improvement is correct. Converting it to a percentage just means multiplying the factor
For the first question a factor of 19 translates into 1800%. To arrive at this result, consider the case where the student gets a score of 30 on the first test and a score of 60 on the second. This is
The first function is f(x) = 3x³ + 4x²  sqrt(x). The other function is f(x) = 5x³[sin³(x)]. Given that the 2nd function had a trig term in it, it can be seen before hand that the derivatives will
