Can you do the DNS course after 10th?
If you have finished Class 10 and you are already planning to pursue your career as a member of the Merchant Navy, then you might be aware of the Diploma in Nautical Science (DNS) program.
Is it possible to join DNS right after Class 10?
The answer is no; you cannot join DNS right after Class 10.
DNS is a post-Class 12 course. For joining DNS through the usual way, a candidate has to be from 10+2/equivalent, having PCM subjects, and meeting all other eligibility criteria. As per the Directorate General of Shipping, the academic eligibility for joining the DNS course is 12th grade with PCM and 60% aggregate with 50% English in Class 10 or 12.
In other words, Class 10 is the start of the process but not the entrance to DNS.
Why Can't You Join DNS After 10th?
DNS is structured in such a way that the candidate must have undergone senior secondary education.
- Academic requirements for joining the DNS program include
- Physics
- Chemistry
- Mathematics
- English
These subjects should be passed by the candidate before taking part in the DNS program at the class 11 and 12 levels.
As per the present IMU information, the DNS program requires 10+2/equivalent with at least a 60% PCM average and 50% marks in English in class 10 or 12.
Thus, merely clearing class 10 is not sufficient.
What Should You Do After 10th If You Want to Join DNS?
If DNS is what you want, the easiest way is that you stick to Classes 11 and 12 in the PCM stream.
A student must choose:
- Physics
- Chemistry
- Mathematics
- English
After finishing Class 12, you may move ahead with all the necessary steps for getting into DNS.
This is an important phase because your PCM results in Classes 11 and 12 will influence your eligibility. The present DGS criteria require a 60% PCM aggregate to be eligible for DNS.
DNS Eligibility After Class 12th
After completion of Class 12, some of the academic prerequisites for DNS include:
- Pass in a 10+2 or equivalent examination from a recognized board.
- PCM as the required subjects.
- Aggregate of minimum 60% in PCM.
- Aggregate of minimum 50% in English in class 10 or class 12.
- Compliance with the specified age criteria.
- Satisfying the necessary medical and eye-vision criteria.
- Clearing the IMU-CET, wherever required.
Gaining the required company sponsorship for the DNS course in the affiliated institutions.
According to the current definition of the DGS, the DNS is a one-year pre-sea training course followed by 18 months of sea service. IMU’s academic circulars for the year 2026 also reveal that DNS admission in the affiliated colleges is being made for sponsored candidates.
Can You Join Any Merchant Navy Course After 10th?
Though DNS is not available immediately after Class 10, there are other training programs in the maritime field that would suit students who wish to join the Merchant Navy after 10th class completion.
An example of this program is GP Rating.
According to the list of DGS, GP Rating is one of the courses that candidates who have done 10th or 12th grade can undertake, subject to certain academic and language qualifications as well as age, health, and training.
However, GP Rating and DNS are two different career paths.
This is because while DNS is specifically a course that leads to deck officers, GP Rating starts from the rating level. Therefore, if you wish to join the deck officers through DNS, Class 12th PCM is the better option.
Can You Become a Deck Officer After 10th?
It is not possible to get admission to the DNS deck-officer pathway right after Class 10.
- As per DGS, there are three major maritime pathways:
- DNS – 12th with PCM
- B. Sc. Nautical Science – 12th with PCM
- GP Rating – 10th or 12th entry pathway
According to DGS, DNS is the fast-track pathway for the deck officer pathway, whereas GP Rating is the rating pathway with a separate advancement system. Hence, students have to make up their minds on whether they are interested in the officer or rating pathway before opting for a particular course.

What Is the Best Route After 10th for DNS?
For a student specifically targeting DNS, the route can be kept quite simple:
- Complete Class 10
- Choose PCM in Class 11
- Complete Class 12 with the required PCM and English marks
- Prepare for and qualify IMU-CET
- Apply for company sponsorship
- Clear the sponsorship selection process
- Complete the required medical examination
- Join an eligible DNS institute
- Complete pre-sea training
- Continue with the required sea training and competency process
The current DGS information lists sponsorship, IMU-CET qualification where applicable, and medical fitness as part of the DNS entry pathway.
What Should Class 10 Students Start Preparing For?
You do not need to start studying at the level of a DNS entrance candidate while you are still in Class 10.
Instead, concentrate on building a strong academic base.
Focus on Mathematics
Mathematics becomes particularly important once you enter Class 11 PCM.
Build strong fundamentals in:
- Algebra
- Trigonometry
- Geometry
- Arithmetic
- Basic coordinate concepts
A strong Class 10 foundation makes the transition to Class 11 much easier.
Strengthen Physics Basics
Pay attention to concepts rather than simply memorising formulas.
Topics involving motion, force, work, energy, and basic electricity will give you useful preparation for higher-level physics.
Keep Chemistry Strong
Class 11 Chemistry becomes considerably broader than Class 10 Chemistry, so make sure your basic concepts are clear.
Improve English
English is not something to leave until the final year.
The DNS eligibility requirement includes 50% English in Class 10 or Class 12, so maintaining a good level of English throughout school is useful.
Is IMU-CET Required After the 10th?
It is not the case that you take IMU-CET right after Class 10 to get into DNS. IMU-CET becomes important when you become eligible to apply to the course.
As regards the DNS course intake in 2026, IMU has held IMU-CET and released its results and rank certificate, and counseling details for the UG course DNS, among others.
Therefore, if you are currently in Class 10, your preparation for IMU-CET is still in the future and not current. At present, you must focus on completing Class 11 and 12 with a good foundation in PCM.
Is Sponsorship Required for DNS?
For the current DNS admission scheme, sponsorship is an important criterion. The current data for nautical officers maintained by DGS requires compulsory company sponsorship for the DNS program.
The circular of IMU for academics, issued on July 16, 2026, also deals with the admissions for DNS 2026-27 in affiliated colleges for sponsored candidates only.
Therefore, in the case of DNS, a student should not be concerned about IMU-CET alone. Sponsorship is another important criterion.
Can Class 10 Students Prepare for Sponsorship Exams?
You can certainly become familiar with the type of preparation required, but there is no need to start intensive sponsorship-exam preparation in Class 10.
A better approach is to:
- Build strong PCM fundamentals.
- Improve English.
- Develop basic aptitude and reasoning skills.
- Read about the Merchant Navy career.
- Understand DNS eligibility.
- Learn about sponsorship companies and their selection processes.
- Start serious entrance preparation closer to Class 12.
This gives you enough time without putting unnecessary pressure on yourself during Class 10th.
DNS Course Duration After Class 12th
The current DGS description gives the DNS pathway as:
- 1 year of pre-sea training
- 18 months of sea time
The required competency examinations and certification process follows the training.
IMU also lists DNS as a one-year program.
The complete journey towards becoming an officer therefore extends beyond the classroom portion of the DNS course.
JMDI Academy for Future DNS Aspirants
Students who are currently in Class 10 have plenty of time to prepare for a future Merchant Navy career. JMDI Academy Dehradun helps Merchant Navy aspirants prepare for entrance and sponsorship examinations, including PCM, English, aptitude, mock tests, communication, and interview preparation.
For a Class 10 student, the immediate focus should remain on building the academic foundation needed for Classes 11 and 12. Serious IMU-CET and sponsorship preparation can be taken up at the appropriate stage.
Merchant Navy Decoded App for Students
The Merchant Navy Decoded App can be useful for students who are beginning to explore the Merchant Navy.
The app provides Merchant Navy-related information and preparation resources, including an IMU-CET test series. Students can use it to understand different Merchant Navy courses, admission routes, and entrance examinations before making decisions after Class 12.
Important Points to Remember
- DNS cannot be joined directly after Class 10.
- You need to complete Class 12/equivalent with PCM for the standard DNS route.
- The current DGS requirement is 60% aggregate in PCM.
- 50% English is required in Class 10 or Class 12.
- IMU-CET qualification is required for the applicable DNS admission route.
- Company sponsorship is mandatory for the current DNS pathway described by DGS.
- Medical and eyesight standards must also be satisfied.
- DNS consists of one year of pre-sea training followed by 18 months of sea time under the current DGS pathway.
- GP Rating is a separate maritime route available after Class 10 and should not be confused with DNS.
- Students targeting DNS after Class 10 should choose PCM in Classes 11 and 12.
Final Thoughts
If you have just completed Class 10 and want to join the Merchant Navy, there is no need to worry about joining DNS immediately.
You cannot join DNS after Class 10, but you can start preparing for it from Class 10 itself.
The most important decision is choosing the right subjects for Classes 11 and 12. If you want to follow the DNS deck-officer route, PCM is the key academic stream. Once Class 12 is completed with the required marks, you can move towards IMU-CET, sponsorship, medical fitness, and DNS admission.
There are also merchant navy routes, such as GP Rating, that accept candidates after Class 10, but they lead through a different career pathway. DGS currently identifies GP Rating as a 10th/12th entry route, while DNS requires 12th with PCM.
For most students who specifically want to become a deck officer through DNS, completing 11th and 12th with PCM is the clearest path.
FAQ’s (Frequently asked Questions)
No. Passing Class 10 alone does not satisfy the standard DNS academic eligibility. You need to complete the required 10+2/equivalent qualification with PCM.
Choose Science with Physics, Chemistry, and Mathematics (PCM). These subjects are required for the standard DNS eligibility route.
Yes. GP Rating is a separate maritime training route that accepts eligible candidates after Class 10. However, it is a rating-level pathway and should not be confused with the DNS deck-officer route.
The two courses have different eligibility and career pathways. You should not join GP Rating assuming that it will automatically convert into DNS later. If DNS is your specific goal, completing 12th with PCM is the more direct route.
No. The 60% requirement refers to the PCM aggregate at the 10+2 level for the standard DNS route. English requires 50% in Class 10 or 12.
You can build the fundamentals early, especially in mathematics, physics, chemistry, and English. However, focused IMU-CET preparation is better done closer to the year in which you become eligible.
For the current DNS pathway, sponsorship remains an important requirement. A good IMU-CET rank does not by itself replace the company sponsorship requirement applicable to sponsored DNS admissions.
Focus on your Class 10 studies, choose PCM for Class 11 if DNS is your target, improve your English, and start learning about the Merchant Navy and DNS admission process. There is plenty of time to prepare for IMU-CET and sponsorship examinations later.
