Now im doin my (b-tech)IT 3rd year in INDIA but i wish to discontinue and do some 1 year cource's in UK so please guide me.........

If you ahve cleared all your current papers, then you can do top up one year degree course in the same line of study. You have to send in your marksheets and apply for particular course. Try in www.beds.ac.uk or www.mdx.ac.uk

sir B tech is a good course and you have good opportunity have patience. concentrate your Btech and after completion your gradution you doing job in India for one or two year then you move to higher study in abroad which is benifit for you.all the best.

Better you complete your degree and then proceed on to UK for MS and related courses. Skipping one year at this stage will do more harm than good.
