ECO driving.

I'm practising "ECO driving" recently.
When I wait to change traffic lights, I usually stop an engine.
Then CO2 is reduced and mileage improve.

My car's mileage is nomaly 9.5km/liiter.
But I refueled today. Then it was 10.5km/litter.

STEP test

I took the STEP test, Grade 2.
Hmm...It was difficult for me.
Because I don't have enough vocabulary.
And I don't know English grammer.

Teacher said "Vocabulary is power,grammer is skill"
I am short of both.

By the way,it was raining and was thundering while taking STEP test.
