Can you do a take away in your head, and use the difference to predict the next number of the sequence? The LU3 Aptitude test only has arithmetic sequences (add a number, and maybe an increment, to get the next number). The links below include alternating sequences and geometric sequences. ONLY arithmetic sequences will be on the test.
Not only do you need to do takeaways in your head, can you multiply/divide/add/subtract in the correct order? There are many more of these items on the LU3 Aptitude test, so practice, practice, practice.
Don’t freak out! All you need to do is “eyeball” slopes and intercepts for linear equations, and be able to translate between formulas, data tables, graphs and verbal expressions. These links will help you get used to the “lingua franca.”
A key item on the math section is measuring the ability to express changes in one variable of an equation, when another changed. This is sometimes called the relationship between independent and dependent variables. Play with these virtual labs, to get a “feel” for what dimensional analysis is all about.
Being able to algebraically manipulate variables is another skill assessed on the Aptitude test. Unlike the Order of Operations section, you don’t need to find a numeric answer on this section, like the Dimensional Analysis section.
There will be 4 long technology passages that will be similar in content to the topics below. Familiarizing yourself with the jargon will help you answer question on the actual Aptitude test.
Tides
Salt Production
Road Construction
Hydroelectric
Computer/Body Parts
Photosynthesis
