>>Can we use "PNG" format images for UML diagrams?
Does it ask for the images to be in a particular format on the exam?
I've always considered JPG and GIF to be more universal formats. I know that whoever is marking my exam will at least have a web brower on their machine that can open a GIF or JPG image. If you have the same confidence with the png format, then
you should be fine.
>>My assigment size came around 339 KB? is it okay ?
It's hard to tell if your assignment is ok based solely on its size. :P
339KB sounds fine, and it shouldn't pose a big uploading problem. I reduced the number of colors in my images and had a jar file that was less than 100K. But 339K doesn't sound too bad in itself.
Good luck!
