English Conditionals

I worked in this website:
http://www.englishclub.com/grammar/verbs-conditional.htm

Those exercises were a little bit complicated but I have all the answers correct (10 out of 10). I never forget the structure for:

First conditional:
If + Simple Present+ will/won't

Second Conditional:
If + Simple Past + Would/Wouldn't

Thrid Conditional:
If + Past Perfect + Would Have/Wouldn't have

I'll never forget them
