Present Tense

[Andy]

Hi,
At school I learnd, to use Present Tense in text summaries.
Now my question. Which tense should I use instead Past Perfect?

For example.
After I had heard about, I did something ...

Or should I use this version in the summary?:

After he heard about, he does something

[Dauersuchti]

I would say, after heraing ...

Muss aber nicht richtig sein

I guess it is better to say:

Ex: "After I have heard that, I do something..."
