Hi
Does the number of subjects above the minimum requirement of 5 in IGCSE affect in any way in terms of higher studies and university admissions?

  Hello MJ,
  
  College/university entry requirements are usually based on required subjects taken, not the amount of subjects taken. We suggest that you check with the universities that you wish to apply to, and get the confirmation on required subjects in accordance with the course you would like to study in the university. In this way, you would have 100% assurance that you have chosen the right subjects for your future studies.
  
  We hope this helps.

Hello,
Can you answer this for me?

Show that the volume of a metal sphere of radius 15cm is 14140cm3, correct to 4 significant
figures.
[The volume, V, of a sphere with radius r is V = 4/3 πr3.]

  Dear Tom,
  
  First let’s solve the problem using the given equation for the volume of a sphere.
  It is V = 4/3* $\pi$ *r³
  As r = 15 cm , $\pi$ = 22/7
  V = 4/3* $\pi$ *(15 cm)³
  V = 14 137.166 cm³
  
  And then let’s see the meaning of the phrase “correct to 4 significant figures”. To determine the significant figures of a number, we have to follow 3 rules.
  
  1. Non-zero digits are always significant.
  2. Any zeros between two significant digits are significant.
  3. A final zero or trailing zeros in the decimal portion only are significant.
  
  We can identify the significant digits of our answer from left to right. According to the above rules in 14137.166 , 4th significant figure is 3. To round this, we will consider the very next digit of the 4th significant figure, which it is 7, and 7 is greater than 5. If the next digit is greater than or equal to 5, we are adding 1 to the given significant figure (round up). So the answer is 14140 cm³.
  
  Hope this will help. We are here for you!

Me and my brother were not good at English from the start. Luckily we got to know about Skolatis revision courses from one of our friends. My brother purchased the English course from his account and we gave our best to improve our English. The course was fantabulous. The videos explained the concepts so well that there was no doubt in us getting an A* in English in 9th Grade.

My daughter Nawal Amir completed her english revision course with igcse center. Words cannot define how comprehensive and supportive the whole course is. The administration and the teachers are prompt and methodical in guidance. Not only that being a parent one doesn’t have to worry about how is the progress of their children as they go according to a timetable with test papers practice along with it. I
wish best of luck to igcse team and a great lot of thanks to Leana especially.
