- Write your ID on the top of your solution file.
- All students are directed to use the font and style of text as is used in this document.
- Don’t use colorful back grounds in your solution files.
- Use Math Type or Equation Editor etc for mathematical symbols.
- This is not a group assignment, it is an individual assignment so be careful and avoid copying others’ work. If some assignment is found to be copy of some other, both will be awarded zero marks. It also suggests you to keep your assignment safe from others. No excuse will be accepted by anyone if found to be copying or letting others copy.
