Why the colour vision step comes last
Colour blindness disqualifies a candidate from every Deck, Engine, ETO and GP Rating role under current DGS medical standards, with no correction accepted — checked before any academic cutoff in the real Merchant Navy medical. Confirming it here, before you've spent anything on coaching or a course, is the highest-leverage five minutes in the whole process.
Frequently asked questions
Which Merchant Navy routes does this eligibility calculator check?
DNS, B.Sc Nautical Science, B.Tech Marine Engineering, GME, DME, ETO, GP Rating, Fitter/Welder and Saloon/Catering — based on your class, stream, PCM and English percentages, age and board.
Does the eligibility calculator include a colour blindness test?
Yes. The final step is a real Ishihara-based colour blindness screening, not a self-report question — a normal result is required before your full eligibility report unlocks.
What if my PCM percentage is below 60%?
You won't be eligible for the August batch, but the February batch becomes an option after an improvement exam, NIOS, or a Class 12 re-attempt. The calculator also shows GP Rating and Saloon/Catering as routes that don't need a PCM background at all.
Is this eligibility check free?
Yes, completely free, with instant results and a personalised next-steps guide.
This tool gives a screening and eligibility estimate, not an admissions guarantee. Confirm your colour vision result with a DGS-approved doctor, and confirm company-specific cutoffs directly before applying.
