Dear Student,

The beginning of your career is when you graduate.

I can provide you a few choices. One of them is yours to select.

• Post-Graduate in Mathematics: Since you already hold a degree in mathematics, you should be familiar with the M.Sc. If you pass the NET and SET exams, you can join any lectureship programme after receiving your MSc. You can also pursue a PHD and a career in research, which will earn you a nice salary and a respectable reputation. SET and NET qualified lecturers are no longer available to educational institutions. There is a tonne of room for research in math. In India, there are numerous institutions that conduct math research. IIT Chennai and IISC Bangalore are a couple among them. Only a few universities, including Pune University, offer research programmes.
• Courses in computers: As a computer programmer, I am aware that those with strong mathematical skills excel in the software sector.
• You can enrol in the MCA programme, where you will learn a variety of computer technologies and receive treatment on par with engineers who hold a BE degree.
• You can pursue an MBA, too.
• Competitive Exams: Now that you have a degree, you are eligible to take any competitive exam. such is the UPSC or any state-level competitive test where you can pursue a career in government. The reason I'm telling you this is because you have a background in mathematics, therefore you should have good problem-solving skills, logical thinking, and solid math practise. As a result, you find the challenging portion of these competitive tests to be simple. And the remaining subjects are all ratta.
• Indian Armed Forces: You can enlist in the Indian Army, Navy, and Air Force. To do so, you must pass an entrance exam.
