Titration help please

I did a practice titration for an upcoming OCR gce chemistry A quantitative (f323), and I messed up my titration.

If has done this, I want to know the correct concentration of the H2SO4?

This was what I had to do:

Determine the concentration of H2SO4

I was provided with Aqueous sodium hydroxide, NaOH of concentration 0.100 mol dm^-3

Phenolphthalein indicator solution

1) I had to transfer 25cm^3 of Sulfuric acid into a 250 cm^3 volumetric flask, make the solution up to 250 cm^3 using distilled water. Then add this to the burette

2) Using a pipette and filler transfer 25cm^3 Of 0.100 mol dm^-3 NaOH (aq) into a conical flask. Then add 3-4 drops of phenolphthalein

Just don't mess up your real one. This is only a practise, so I doubt you're going to get the same volumes in the real thing. The best thing to do is ask for tips on doing the titration instead of this.
