Can I get tax Benefit on Interest paid in same Financial year but before posession

Hi,

If I take possession on 15-Jan-2015, can I take the advantage of complete interest paid (with a cap of 2 Lacs) before this date but in the same financial year (between 01-Apr-2014 to 14-Jan-2015) under section 24 ?

Or would it be like this

a. Complete interest amount paid between 15-Jan and 31-Mar   +

b. 20% of the interest amount paid between 01-Apr to 14-Jan

Please help.

Thanks,
