Entrance Exams for Mathematics PhD
| Exam | Conducting Body | Used For | Difficulty |
|---|---|---|---|
| CSIR-NET (Mathematical Sciences) | CSIR/NTA | UGC/CSIR fellowship; most universities | High |
| NBHM Scholarship | DAE/NBHM | TIFR, ISI, CMI, HRI, IMSc admission | Very High |
| TIFR GS | TIFR Mumbai | TIFR PhD only | Very High |
| CMI Entrance | CMI Chennai | CMI PhD only | Very High |
| ISI Admission Test | ISI | ISI Kolkata/Delhi PhD | Extremely High |
| GATE (Mathematics) | IITs | IIT/NIT PhD with stipend | High |
Preparation for ISI/TIFR Maths Entrance: Start with a thorough command of real analysis (Rudin), algebra (Dummit & Foote), and topology (Munkres). ISI entrance has very high cut-offs and tests deep understanding, not just formula application. Practice past papers for at least 3 years before the exam. Joining the ISI-CMI entrance coaching programmes available in Kolkata, Delhi, and online is strongly advised.
Career Pathways After Maths PhD
- Post-Doctoral Research: 1–3 years post-doc at IITs, ISI, TIFR, or international universities
- Academia: Faculty at IITs, IISc, IISERs, CMI — starting salary Rs 1–1.5 lakh/month
- Finance and Quant: Quantitative Analyst, Risk Modeller at banks and hedge funds — Rs 20–50 lakh/year
- Data Science and AI: Research Scientist at tech companies
- Cryptography and Security: Industry and government roles
- Government Research: DRDO, ISRO, BARC, NABARD research divisions
