Newton Online Tests

I have been called to the cognitive/maths tests for a few companies now, but am really out of practice with my maths (it's been 4 and a half years), so keep getting rejected after the maths tests despite a strong CV. I was wondering what the best ways to practice are as I am struggling to find resources and then just going round in circles because I can't improve and just get really stressed during the tests. 

Please may you recommend some resources to help me quickly but effectively improve my maths (I have to do my next online maths test on Sunday).

Thank you!!

Sorry to hear about this!

I'm sure you'll get a few recommendations of where to practice, but I wanted to emphasize a couple of other points:

  1. Don't assume that only the math scores are the issue. Tough recruiting cycles + not having a referral + a CV / CL that are not as good as you think + a role that is not a great fit for you >>> all of these things could explain you not passing screening too
  2. Re maths - practicing tests over a longer period of time does lead to improvement. This might be stating the obvious, but it's just an encouragement that the more hours of practice you put in, the better you'll get
  3. For best results, practice across different test formats from different firms. They all test similar things but they might use a slightly different format, and by practicing multiple types you'll develop more flexibility

Adding here also a list of the most common formulas that show up in tests and cases:


Best,

hey there :)

For Newton-style tests the fastest way to improve is short daily sprints with a timer. Use the free packs on AssessmentDay or PracticeAptitudeTests and a few GMAT mental maths videos on YouTube. Focus on percentages, ratios and quick graph reading, not long study sessions. Two or three 10-minute drills per day usually help a lot and reduce stress because you get used to the timing.

best, Alessa :)

1. Use GMAT preparation materials. The official ones. Ignore any other gmat prep, as it is of lower quality.

2. Practice every day. This is life strength building. Doing 2h on a random Saturday doesn't move the needle. Practicing 15-30 minutes 3-5 times a week "builds muscle". And with time extend the period, as being able to perform for a longer period plays a role on your effectiveness level.
