They cannot. Test scores are either marks or percentages based on marks (out of the total) and so are discrete.
Discrete.
The answer depends on what the experiment is about. For example, if you believe (or want to test) that pupils' scores in English tests depend on their scores in maths tests, then the independent variable is the maths score. But if you believe that the English scores influence their maths scores then the independent variable is the maths score.
The average score on an IQ test is about 100. If you score higher than that, your score will be above average.
For a one-sided test there is a 1 in 200 chance (0.5%) of getting a result which is at least as extreme.
The independent (or explanatory) variable is changed to test the prediction,
Discrete.
A test score is generally discrete; one can score 89, 92, or 50, but one wouldn't score something like 82.3455456467. Even if the correct/total division resulted in a non-integer, it'd be discretized during the rounding process.

The z-score, for a value z, is the probability that a Standard Normal random variable will have a value greater than z.
the test variable is the independent variable.

Analysis of covariance is used to test the main and interaction effects of categorical variables on a continuous dependent variable, controlling for the effects of selected other continuous variables, which co-vary with the dependent. The control variables are called the "covariates."
The independent variable.
The one variable that is purposely changed to test a hypothesis is manipulated variable
An operational definition of a variable is that which defines a variable in terms of operations that are used to measure it. This allows different investigators to perform the same or similar experiments when investigating a phenomenon. For example, a score on a standardized IQ (i.e., intelligence quotient) test might be the operational definition of the variable "intelligence."
If the Z Score of a test is equal to zero then the raw score of the test is equal to the mean. Z Score = (Raw Score - Mean Score) / Standard Deviation
The two main variables are the essay score and the amount of multiple choice questions you answered correctly. CollegeBoard also curves the scores based on how well other test takers do.
