# Explanation:
## Step1: Sum all test scores
$100 + 75 + 84 + 86 + 66 + 43 = 454$
## Step2: Calculate the mean
$	ext{Mean} = \frac{454}{6} \approx 75.7$
## Step3: Order scores for median
$43, 66, 75, 84, 86, 100$
## Step4: Find the median
$	ext{Median} = \frac{75 + 84}{2} = 79.5$
## Step5: Compare mean/median relevance
The low score 43% skews the mean down; the median is less affected by outliers, so it better represents typical performance.

# Answer:
Mean: $75.7\%$
Median: $79.5\%$
The median gives a better overall score for Jonathan's performance, as the low outlier score of 43% distorts the mean.
