SHL reasoning foundations
Read numerical information, find patterns, and work through rules with ten lesson and practice pairs.
Independent practice, not an SHL test or endorsed course. Question formats, timing, adaptive difficulty, and scores differ. Check your invitation and use SHL’s official practice for the test you will take.

Your path
Read the method, then put it to work.
-
Work with percentages and ratios
Identify the whole, find the useful parts, and keep quantities in proportion.

Read tables and check conclusions
Read labels and units before calculating, then separate supported claims from missing information.

-
Find the rule in figures
Track what changes, test the rule against each example, and predict the missing figure.

-
Separate facts from assumptions
Follow only the links the statements support, then identify the gap in an argument.

Combine clues without guessing
Place fixed information first, rule out impossible combinations, and check every condition.

Try a harder setting, apply the method in another practice, then review what changed.

Join the right rows
Match product labels across the two tables. Calculate each profit before comparing, or find the revenue gap before calculating extra units.
Lessons & practices
LessonPracticeAfter your round
Explain which columns you used and ignored. For a target, check that your answer reaches it and one fewer unit does not. -
Combine marks without counting twice
At Extended Level 5, keep marks that occur in exactly one of the two input cells. Check the rule across the complete rows or columns, depending on the pattern.
Lessons & practices
LessonPracticeAfter your round
Point to an overlapping mark that disappears. Explain why adding every mark would give the wrong result. -
Turn first, then combine
At Extended Level 6, follow the turn before joining or removing marks. Test the order of these operations against a complete row or column.
Lessons & practices
LessonPracticeAfter your round
Name the turn and the combining rule separately. Show why combining first and turning afterward would change the answer. -
Separate possible from necessary
Use the clues to keep more than one valid order in mind. Read whether the question asks what must, could or cannot be true.
Lessons & practices
LessonPracticeAfter your round
For a possible claim, give one valid order. For a necessary claim, try to build a counterexample and identify the clues that block it. -
Change the percentage base each time
Apply the first percentage change, then use the new amount for the second. Once comfortable, try percentage points and finding an unknown percentage.
Lessons & practices
PracticeAfter your round
Write the two multipliers and name each starting amount. Explain why equal percentage increases and decreases do not cancel.
