You don't have to wait for Class 12 to finish before getting ready for the armed forces. The NDA has two written papers: Maths and General Ability. Clear those, and you still face the SSB interview. That's a lot to fit in, and a student who starts in school has years for it, not a few months.
Ask any NDA topper what took the longest, and most will say Maths. You can't just read a formula and move on. You have to use it on a few hundred sums before your hand starts doing it without you. English and GK are slower in a different way.
A teacher who answers doubts the same day makes a bigger difference than people expect. A student stuck on one trigonometry problem can lose a whole evening alone. With someone to ask, that evening goes to the next chapter. Weekly tests do something similar, because they show a student which topics are slipping before the real paper does.
The SSB looks for things a written paper can't show. In the group tasks, the assessors say very little and watch. One candidate cuts in on everyone. Another listens first and then makes the point that moves the group on. A third stays level when the plan falls apart.
Fitness can't be left to the end either. A month of running before the physical tests won't give you stamina, because it only comes from months of regular exercise. Start in Class 11 and by the time you're sitting in a long study session, you'll find it easier to stay awake and concentrate.
Schoolwork doesn't have to suffer. Most students already have a rhythm of classes, homework and exams by Class 11, and exam prep can fit around that. An hour of NDA study after school, plus longer sessions at weekends, adds up to a lot over two years.
Many students pick the wrong books or change their routine every few weeks. A mentor who has seen earlier batches can point out these mistakes quickly. That saves time, and time is the one thing a school student has plenty of if they start early.
Keep every test paper, and you end up with a diary of your own progress. A few months in, flip back through it. Geometry might have gone from half marks to nearly full. Algebra might still be dropping the same silly marks. And you can see if the minutes per question are creeping down.
None of this takes anything special. Study a little every day. Look back at old chapters now and then. Get half an hour of running or football in, and go to bed on time. Keep it up for a year or two and you'll be surprised how much has piled up.
