D20 modern questions about feats

[Nosta]

I need to know how many feats i should have at level six, if i put three levels in strong hero, there level in the martial artist advance class , with a starting occupation that gives a feat . i'm just not sure how many i should have

You get two feats at 1st level (one of which is the Occupation feat), one feat at 3rd level, and another at 6th level. If you're human, you'll have three feats at 1st level.
You'll also be getting a bonus feat from strong hero at 2nd level, and a bonus feat from martial artist at 6th level (3rd level in the advanced class). These feats must be selected from the bonus feat list of each class. This brings you up to a total of seven feats by 6th level, and is not counting proficiencies.

You'll also receive strong hero talents at 1st and 3rd levels.
