Wow, Nensi, you made me very happy by correcting my mistake.
I felt something was wrong and wanted to correct it as you did, but than I wasn't 100% sure, so I thought: Ah, Nensi will corect me If I made a mistake ( as you will probably have to do it again, since I am very bad with the IF clauses
)

If I make a mistake, she will corret it.
If I made a mistake, she would correct it.
If I had made a mistake, she would have corrected me.
There are many types of if clauses, depending on the situation, these are some examples.
The best thing to practice languages is to talk, read a lot and watch TV.
In general the knowledge of different foreign languages in Slovenia is high compared to other countries. Luckily we didn't have money to synchronise the films so we can still listen to the original languages spoken in them.
