hope u have got the syllabus of the test. the questions are quite easy provided if u have even the slightest of innovative mind and a bit of skill in drawing..... there will be some questions in which u have to logically analyse 2d and 3d shapes eg. which of the two shapes fit together etc. there will be some designing questions which are the important ones. last year it asked to design a walking stick for blind with the features u think are imp., a movable kiosk or store for a fruit seller and a wall fresco to be installed in a science museum.. there will be some other questions testing ur common sense like which direction shud windows of house be to avoid mid day heat etc....
actually the drawing does not matter as much as your ideas.... think nicely and innovatively and you shoud cruise through the exam....
i guess u wont get any sample paper on the net..
All the best!
Hope the answer helped.
