Tax payment after resigning from a company and going for higher studies?

Hi I am an Indian resident. I was an employee of an IT firm in India for the past 3.5 years until i resigned shortly 2 weeks back as i would be going for higher studies a couple of months later. Mean time i would be preparing myself for the study and not to be engaged in earning. So i need to know do i need to pay the tax after i resigned from the company and the fact i am no more a salaried person. If yes what’s the structure like?

What happens when Income tax is filed after filing deadline?

I e-filed my 2009/10 (Assessment year 2010/11) tax return (ITR-1)on 18 April 2011. There is no balance due or refund on the return and my salary income was well below than 1,60,000. I just wanted to learn how to file a tax return so that I could do it myself for 2011/12 assessment year tax return. Please advice if I would be liable to any late filing penalty?
