Since you just completed your 10th standard . As you have mentions (air-force robotics any )Now to the serious part, depending on your will power, determination, Financial and economic status there are different paths that you can take. There are about 679 Engineering colleges in Tamil Nadu out of which 572 are private and 107 are public colleges. One of the topmost ranked Engineering colleges in Tamil Nadu is the IIT Madras and VIT Vellore.
1. ITI trade.This can be done after 10th std. It’s a 2 year certificate course. Course fee will be nominal and once you have completed it you will be ready to be employed any Dealer or mechanic shop.
2. Diploma in Engineering is Awarded to students who can complete 3 year Diploma from any Government Polytechnic or Private Polytechnic.
3. Having completed 10th std, You can Join 2 year PUC/12th with Science subjects Physics Chemistry & Mathematics. Working hard and scoring high in PUC Board exam as well as NEET orState entrance examination to get good Ranking. There by opening the doors to get into any Government or Private Engineering Colleges. This will Award a Bachelors Degree in Engineering ( Mechanical or Automobile) after 4 years completion.
Since you mentioned # air force you can look for NDA after 12th, Kindly check if girls are eligible after 12th. But I am sure after your graduation you can take up CDS for Air force or Defence services
As you may be sensing, 10th is a BIG time to start off your academic career. So I suggest a focus on Rudiments. And the more you understand MATH, the better you will build on the foundations of science and technology as the years progress! Starting with Algebra and Trigonometry, your "basic gateway" in science/tech will quickly show you the foundation you need.
I would recommend the physical/visual/practical insight of GEOMETRY as well.
Dont just think about getting good grades... REALLY understand this stuff... It makes whats coming easier.
These can be overwhelming lessons , but trust me.. the better you know them... the easier the other stuff gets! And your STEM studies are coming up quick!
Which brings me to the second topic...
SECOND ( topic ... haha)
Start learning about what is available to you and where you want to be. I recommend STEM or pre-engineering programs through your school... you may not know about them... but they are probably there. Talk to the school counselor... and if they aren't compelling... ask them to research and get back to you! Your future may depend on that information.
The world depends on digital processing and that wont go away! Almost every technical career will require some knowledge of processors and programming.
Topic one will branch into "number theory" where binary , hexadecimal, etc supplements your DECIMAL way of thinking. This knowledge is you "language" among the processors that you will make "spring to life"
There are a ton of education based kits and programs, FIRST robotics clubs can help find people to team up with and learn together... Mindstorms, Arduino, Raspberry... all have learning modules that are fun and can begin your journy into the logic world.
START your career right... BALANCE .
GO be a kid! enjoy the world around you. Find ways to make your life rewarding, including your career.... study with a club...
This is too often not considered. Your success does not just involve meeting career and life goals, but finding a rewarding path to those goals...
Rudiments- STEM - Balance will launch an ideal career every time
