If you do DNS then you will get 1 year's Diploma certificate after which you can pursue B.Sc in the same via distance mode. This degree will not be a regular degree. When you do DNS course you have two semesters of 6 month each. After the completion of these semesters, you have to join the ship as a Trainee Deck Cadet with a training period of 18 months which will include your 3rd, 4th and 5th semesters. Once you complete your training period on board ship, you have to do modular advance courses as well as a 4-month competency course for a foreign going ship. Once you have done all of this, then you have to appear for 6 written exams and 3 orals which will be conducted by DG Shipping of India. Once you pass the same then you will get the certificate of competency, which will help you to join a ship as the second mate. Along with this, you have to give 3 written exams which will be conducted by the university for the B.Sc degree certificate. Fees of this course is around 2.5- 4.5 lakh rupees, it depends from institute to institute.

Yes, this will definitely affect the rank. This can increase or decrease your ranks subjected to the correctness of your guess work. Now suppose you have attempted total 50 questions, in which 10 questions were attempted by using your guess work. Now let's see what will happened?
1. Case-1 : If 10 questions are wrong. Than your score will be 40*4-10=150
2. Case-2 : If 5 questions are correct than your score will be 40*4+5*4-5=175
3. Case-2 : If 2 questions are correct than your score will be 40*4+2*4-8=152
4. Case-4 : If you have not attempted any question by using guess work than score will be 40*4=160
So from above it is clear that guess work can be benefited up to some extent but not recommendable.
