Questions & Answers about kono mae no shiken de seiseki o homerarete, jishin ga demashita.

What does この前 mean in この前の試験で?

この前 literally means the last time or recently. Here it’s followed by の to modify 試験, so この前の試験 refers to the exam you just took or the most recent exam.

Why is the particle で used after この前の試験?

In this sentence で marks the context or occasion in which something happens. 試験で tells us that the following action (being praised) occurred in connection with that exam, not at a physical location.

What grammar is shown by 成績をほめられて?

This is the passive form of 褒める (to praise). 褒める becomes 褒められる in the passive (‘to be praised’). The ending -て then links this clause to the next one, indicating cause or background.

Why does ほめられて use the て-form instead of the past た-form?

The て-form here connects two clauses to show that the second clause is a result or consequence of the first.
成績をほめられて、自信が出ました
= I was praised for my grades, and as a result I gained confidence.

Why is 自信 followed by が rather than は?
