sister Gul

its very easy
first read the thesis paper of all other people
who have done research...on the related subject

at the end of every thesis...sources are written
then u can get infromation, material easy

thesis are available in every library section

but that is a very detail and long studies

secondly, you must get favour,support of some
senior teachers bcz they have to approve your thesis
if any of them reject your thesis

you will not be ableto get approved

thirdly, if you work under, or showing how
much seriously you are working for your
research other teachers definitly get inspired
even they are not willing to sort you they
will support you

lastly, thats all your own effort
you may get alot of material but
you have to write in your own simple way
not a copy paste,,,,

Best of Luck,,,
