Income tax return in case of education loan

Question:- I have a doubt regarding the income Tax return

I passed my B.tech in June 2011, for completing the education I took the Education loan of 4 lac. And joined company as Software Engg. on 11 July 2011,

Now during filling the details of my investments (for calculation of TDS) I showed the amount of interest put by bank from  11 July till 20 Jan which is 25729.

Can I get rebate on income tax for the complete financial interest from 31 mar 2011 to 31 mar 2012?

So tell me the procedure to fill education loan information in income tax Return and what documents I should submit as proof.

And also tell me that ,how much amount, from my loan EMI will be properly counted by the income tax department.
