Introduction 

If you’re pursuing or considering the online BS Degree in Data Science from IIT Madras, you may have come across the term "OPPE." OPPE, or the Online Proctored Programming Examination, is essential for students taking programming-focused subjects within this program. It plays a crucial role in assessing students’ coding abilities and understanding of core programming concepts. In this blog, we’ll dive into OPPE, explaining its structure, requirements, and how it fits into the IITM BS Data Science curriculum.

What is OPPE ?

The Online Proctored Programming Examination (OPPE) is a proctored online assessment conducted for students enrolled in programming courses within the IITM BS Degree in Data Science. Students can attend the OPPE exam online using their Laptop

OPPE is mandatory for programming subjects, ensuring that students possess the programming proficiency required for success in the data science field.

OPPE consists of two exams per programming subject: OPPE 1, and OPPE 2. If a Student has passed in OPPE 1 then OPPE 2 isn't Mandatory. Passing OPPE is required to pass the subject overall, and failing this exam prevents students from progressing in the course. These assessments are crucial for evaluating a student’s practical coding abilities.

Programming Courses Requiring OPPE at Each Level

In the IITM BS Degree in Data Science program, programming courses are spread across three levels: Foundation, Diploma, and Degree. Each level includes specific programming subjects for which OPPEs are mandatory:

Foundation Level:

Python

Diploma Level:

Java

DBMS

PDSA

MLP

SC

Degree Level:

C programming

Big Data

Each of these courses includes OPPE assessments, ensuring students gain practical skills and hands-on experience in programming relevant to data science

Required things for OPPE

• A Laptop / Desktop System which meet the Requirements of OPPE

• A Stable Internet Connection 

• A Peaceful environment for OPPE , no interaction with others.

• To check the Requirements IITM conducts a test called SCT (System Compatibility Test)

• Your SCT should be Passed, you can check the SCT status in The My Current Courses in Dashboard 

If your SCT isn't approved then you wouldn't be alloted OPPE slot

• check your OPPE Mail to ensure all the things like exams timing etc.

Structure of the OPPE

OPPE follows a standard structure in terms of scheduling, format, and grading:

Number of OPPEs: Each programming subject has two OPPEs (OPPE 1 and OPPE 2). OPPE 1 is mandatory, while OPPE 2 is optional, giving students an opportunity to improve their scores.

Format of the Exam: The OPPE typically includes 4-5 programming questions designed to test practical coding skills in a real-world context.

Time Limit: Each OPPE is time-bound, with a duration of 2 hours (120 minutes).

Passing Requirement: Passing the OPPE is mandatory to pass the programming subject, so students need to be well-prepared.

Minimum Marks 40 out of 100

Items allowed and not Allowed in OPPE

To maintain integrity and consistency, OPPE has strict guidelines on what items are permitted or prohibited during the exam:

Allowed:

Computer System: A single computer with a stable internet connection.

Specified Programming Environment: Only programming tools approved by IIT Madras such as Dry Running the code 

Not Allowed:

Additional Electronic Devices: Mobile phones, tablets, and other computers are prohibited.

Unauthorized Reference Materials: Only materials specified by IIT Madras are permitted; all other books or online resources are not allowed.

Communication with Others: Discussing or seeking assistance during the exam is strictly forbidden.

How many times you move your head is also noted so there isn't chance of cheating 

Students should check updated exam guidelines before each OPPE, as IIT Madras may adjust the rules based on course requirements.

How to Prepare for OPPE

Success in OPPE requires careful preparation, particularly since the exam is a time-bound, programming-focused assessment. Here are some preparation tips:

Consistent Coding Practice: Regular coding practice is essential, as OPPE questions require practical application of programming concepts.

Problem-Solving Skills: Practice solving different types of coding problems, especially ones that focus on algorithms, data structures, and data handling in Python.

Familiarize with Allowed IDEs: Get comfortable with the programming environments allowed by IIT Madras to avoid any issues on exam day. It is the same as the GRPAs one. 

Mock Exams:  try mock exams or previous OPPE questions, as they can give a better understanding of the question format, difficulty level, and time management required.

IITM usually provides pyq and mock test in the dashboard. So Don't Forget To Check them

Let's Learn Courses: If you want more detailed and language friendly content for OPPE subjects such as Python and other courses you can check out Let's Learn Courses. These courses provide learner a more detailed content, so the learner can ace their OPPE exams.

Common OPPE Challenges

While OPPE is a valuable part of the BS Degree program, it does come with challenges:

Technical Requirements: A reliable internet connection and compatible software setup are crucial for a smooth exam. Make sure to test your system beforehand.

Exam Anxiety: Since OPPE is a high-stakes, timed exam, it can lead to stress. Practice regularly to boost your confidence, and consider relaxation techniques to help manage exam pressure.

Time Pressure: Working within a 120-minute time frame can be demanding. Develop a strategy for tackling questions based on difficulty and focus on improving speed through practice.

Tips for Python OPPE1

There will be 5 questions in OPPE and you have to solve any 4. So there is ~23 minutes for each question to solve.

You can spend 3 min to read/understand each question and if you get some intuition about how to solve in the first 5 min then you must start writing code, if it is taking more time skip this question and move to next.

Have a pen and paper handy at all times, break down the problem question into manageable-sized pieces, write pseudocode for each of these pieces, then start writing code in an editor, and less than five minutes has probably passed.

If you forgot how some built-in function works, then do: print(help(func_name))
