Hi Mike,

Can you please do practise test 7, section 4, question 29 (Whats the fastest way to do it which doesn’t involve using the distance formula for every answer option)

## Whats the best and fastest way of doing Practise test 1, section 4, question 23?

Whats the best and fastest way of doing Practise test 1, section 4, question 23?

Would it be calculating the ratio of all the options and then comparing it to the Human Resources ratio?

Thanks!

## Hi Mike. Can you please explain Practise test 1, section 4, question 14?

Hi Mike. Can you please explain Practise test 1, section 4, question 14? I figured out that the range was the largest change (but only by physically calculating the mean and median etc.)

Is there a better way to do this?

Also, I’d just like to say THANK YOU THANK YOU THANK YOU for this book it really is amazing!!

## Practice test 2, section 3 Q10

Practice test 2, section 3 Q10, the answer is C (which you can easily obtain by plugging in x = 0) but is there another way to do or it some other logic you can use?

Thank you!

Hey Mike, could you please help me with practise test 8, section 4 question 38? If you simply plug in P as 152, it’s easy to get the answer. However, im not sure what “if P approximates the values in the table to within 10 micrograms per milliliter” exactly means? How does that statement help me to solve the question or change the numbers I’m inputting as P?

Thank you so much!

## How would you do practise test 8, section 3 question 11?

Hi Mike. How would you do practise test 8, section 3 question 11? Can you explain the whole polynomials to an odd/even degree etc. The collegeboard answer was a little confusing

Thank you!

## What’s the fastest way to do question 9 from practise test 2 section 3?Thanks!

## Hi Mike. Just wondering if you had video solutions for the algebraic manipulation practise questions?

## What’s the best and fastest way to do practise test 3, section 3, question 15?

What’s the best and fastest way to do practise test 3, section 3, question 15? How would you interpret the equation? (which I find very confusing and difficult)

Thank you

## How would you use backsolving to solve practise test 2, section 4 question 29?

Hello, I know you’ve already solved practise test 2, section 4 question 29 (by either using your graphic calculator or by looking at the equation of a parabola) but how would you use backsolving? Lets say I try in option C and im getting y as 3 (which means my equations do NOT have 2 real solutions), how do I know whether to try out option B or D next?

Thank you so much!

## For practise test 2, section 3 Q6, how exactly could I use backsolving to solve this?

Hi Mike! For practise test 2, section 3 Q6, how exactly could I use backsolving to solve this? Lets say I start with C and I plug in 8. My gradient of line l is 2/5. If I plug in p as 8, I’m getting gradient of line k as 4/8. Do I now compare the fractions? How do I know if I should try plugging in a bigger or smaller number to get closer towards 2/5 (initial gradient)?

Thanks!

For the official practise test 2, section 3, question 4 is listed as a “plugging in” question.
So when I tried it out, I substituted 1 for both variables a and b. That easily allows me to pick option A.
However, one of your rules was to never plug in the values 0 and 1, yet 1 was a viable option for this question.
So how can I know when plugging in 1 will be okay and when it’s a bad idea? Also, is my method correct for this question or would you suggest another way? Thanks so much!
