• Use matrices techniques for solving systems of linear equations in the different areas of Linear Algebra.

Question paper pattern:

• Each full Question consisting of 16 marks
• There will be 2 full questions(with a maximum of four sub questions) from each module.
• Each full question will have sub questions covering all the topics under a module.
• The students will have to answer 5 full questions, selecting one full question from each module.
