Highly likely questions calculator paper maths edexcel june 8th

Looked over predicted Higher paper,likely question subjects are:

Compound Interest
Standard Form
Reverse Percentage
Simultaneous Linear Equations
Recognise the shapes of functions
Trigonometry
Circle Theorems
Direct and Inverse Proportion
Quadratic Equations
Sine and Cosine Rules
Hard calculator Questions
Area of Circle
Circumference of circle
Solving equations
Solving Inequalities
Trial and improvement
Nth Term
Solving Simultaneous equations graphically
Surface area of triangular prisms
Upper and lower bounds
Enlargement by negative scale factors
Congruent triangles
Bisecting an angle
Loci
Ratio
Vectors
Histograms
Stratified Sampling
Pythagoras' Theorem

Vital to revise these, almost certain these will be in the paper, variety of D-A* question subjects that are very likely to be in there
What's your weakest topic?

Does anyone want some practice questions on these topics I can go through the steps of working out too if you'd like.

A maths teacher in my school sent an email which was similar to this list but if you have mathswatch it has the number of the videos so this list should help.

Yeah got the list and mathswatch is very helpful I've got some predicted questions too from papers

Let's have a look at simple and compound interest,
Q: Here are 2 schemes for investing £2500 for 2 years.

Scheme A gives 4% simple interest each year.

Scheme B gives 3.9% compound interest each year.

Which scheme gives the most total interest over 2 years?

Working out for scheme A
Simple Interest:
(4/100) x 2500 = 100
For 2 years interest = 100 x 2 = 200
So 2500 + 200 = £2700 (this is the total answer for scheme A) - SIMPLE INTEREST calculation method.

Scheme B
Compound interest
= 100 + 3.9% = 1.039 as a multiplier
So, 2500 x 1.039 squared = £2698.80

Therefore scheme A gives the most total interest. 4 marks. :h:

Standard Form

Work out the value of (7.5 x 10 to the power of 4) x (2.5 x 10 cubed)
Give your answer in standard form.
Well let's be grateful for having our calculators

Step 1) 7.5 x 10^4 = 75000

Step 2) 2.5 x 10^3 = 2500

Step 3) 75000 x 2500 = 187500000 <-

Now, we have to convert this answer to standard form. I would say the way to do this is that we know standard form must start with a number (even a decimal number) between 1 and 10. Therefore get 187500000 and place the decimal place to make it 1.87500000. Now, to make it standard form, move the decimal place right,all the way to the last 0. How many times did it move? 8 times, so the answer is 1.875 ( because this is the decimal number we will use) x 10 to the power of 8. Its worth getting these 2 marks and not making a little error. Costly because when standards form comes up there are usually a couple of questions on it, so all in all probably 4 marks. :smile:
