Given your requirements, it's challenging to find stable jobs that offer at least 30,000 a month for a 16-year-old student who has just passed 12th PCM. Most jobs for teenagers are part-time and pay hourly wages. However, I'll suggest some potential options and college courses that could lead to better-paying jobs in the future.

Potential Jobs

- Tutoring: You can offer tutoring services to younger students, leveraging your knowledge in PCM subjects. Experienced tutors can earn up to 19.40 per hour.

- Part-time jobs in retail or food service: Many retail stores and food establishments hire teenagers for part-time work. While the pay might not be 30,000 per month, it's a good way to gain experience and build skills.

- Online freelance work: Depending on your skills, you can explore online freelance work, such as content writing, graphic design, or social media management.

College Courses for Better-Paying Jobs

To increase your chances of getting a better-paying job, consider pursuing a college course in a field like:

- *Engineering*: With a strong foundation in PCM, you may be interested in pursuing engineering courses like B.Tech in Computer Science, Mechanical, or Electrical Engineering.

- Computer Science: Courses in computer science, such as BCA or (link unavailable) in Computer Science, can lead to well-paying jobs in the IT industry.

- Data Science: With the growing demand for data scientists, courses in data science or analytics could be a promising option.

Salary Expectations

Keep in mind that 30,000 per month might be ambitious for a 16-year-old student, especially without significant work experience. However, with the right college course and skills, you can increase your earning potential over time.
