Harikancha, I don't know the validity of 1 year pre-MSC course at KU. I think they started it recently. TU degree is definitely valid. You may have to contact the university for it. You should also be able to get info. from American Center at Gyaneshwor. Did you do your undergrad from TU? I did M.Sc. is zoology from TU and now doing MS in Forestry.
