Internal term *score calculator* denotes algorithm, which is responsible for computing overall score (correctness) of a submitted solution from the results of individual solution test. Each exercise is given a calculator name and associated calculator configuration (stored in DB text column as Yaml), which is used to initialize/prepare the calculator before it is used for computing the score.

We have implemented three calculators so far:

## Uniform

Trivial algorithm, which computes the overall score as arithmetic average of individual test scores. This calculator has no configuration.

## Weighted

Computes overall score as weighted average of individual test scores. The calculator expects that the weights are stored in the configuration in the following format:

```
testWeights:
    "Test 01": 300
    "Test 02": 200
    "Test 03": 100
```

The keys are test names (must correspond with the `name` column of the `exercise_test`) and the values has to be integers.
