This Guide is designed for helping the students to perform better in various practical Courses. It describes the structure of a good laboratory report, outlines the different

sections of the report and explains the need for each of them. It also introduces some

standard conventions and rules for writing reports of professional quality. The quality

of your written report will strongly affect your grade for the course.

EVALUATION OF PRACTICAL WORK

Each student will be required to perform the experiment individually.

Student will be required to write theory, algorithm, program, outputs etc. during

practical session itself.

Each experiment will be marked by the teacher on the basis of experiment

performed and write up on the same day. These marks will account for 40% of the

sessional marks.

Sessional marks will also include VIVA and Attendance marks as per rules.

GOOD LABORATORY PRACTICES

You must develop good laboratory habits by keeping complete laboratory notebooks.

Keep all your notes about the lab procedures and data in this notebook in pen. It is always better to read experiment in advance. The expectation is that you will work individually on separate computers. Each of

you will write a separate report. Please bring your lab manual to the lab on every turn.
