hello aurko you have to demonstrate one year tuition plus one year living expenses in the bank 28000 is enough only to cover tuition , you have to keep the 10000 for living, the salary certificate of your parent is a proof for future funding.
I had read a form somewhere on this site , where a person had shown enough funding for first year tuition and regarding the 10K living expenses he wrote a letter in his file stating that his sponsor would make that amount available monthly.. he got his visa , I don't know whether that would work .. but just giving you an idea..they also need 3K for ticket in the bank .
