Can you do this? Of course, you can do this! Why not? A budding soldier and a hardcore aspirant have the zeal to do many things in life. After 10+2 or after graduation, you want to join the Armed forces and serve this nation. That is itself a great inspiration and motivation enough to succeed all the way through. What I am presenting to you here is just a plan. Sticking yourself to this procedure religiously will surely give you many wonderful results. Take a print of this and maintain this routine. Do not forget to read the Important Points written in the end. They are mandatory.

Note: T = Theoretical questions, N = Numerical questions, B = Both theory and numericals.

Important Points to remember:

1. Everyday you have to go through Polity and Current Affairs without fail.
2. Every alternate day (as said in table above), you will study History. The day you do not study History, in its place, you will study Geography. (The cycle will be Day 1 as Geography, Day 2 as History, Day 3 as Geography, Day 4 as History and so on…)
3. Once in every two days, you study science subjects. If you observe carefully, day 1 is of Physics, day 2 is of Chemistry and day 3 is of Biology. Likewise you will go through in a cycle.
4. That means, every single day, you will go through not one, but a set of two to three subjects alternatively. The only thing that will stay all 50 days is about Polity and current affairs.
5. Remember, here, the number of hours include all kinds of preparation. Not just reading but also solving and practicing few sets of questions in it too.
6. Avoid large numericals. They do not come in exam. If you sit on them, you waste time. Restrict yourself for basic information and complete conceptual analysis. However, formulae are all absolutely important.
7. Once a topic is done, do keep sets of copies of all of the preparatory notes at a separate place. Once every six days, gift yourself some free time if you think you really worked hard.
8. Do not go through deep in anything. Catch the concept as the main motto.
9. Use NCERT books and SSBCrack Books as your reference to cover the main things. Remember, do not stress yourself. Stress creates fear – something that eats all your chances of being qualified. So, keep interest.
10. No matter how much ever prepared you are, if you didn’t solve 5 practice GS sets before exam, all will go in vain.
11. The procedure to study each and every subject, in order to grab maximum of it, I have presented in various Articles. Please have a look at them.  
12. No pain. No gain.

Jai Hind!
