Computer Engineer

Hello Pradeep,
It's good to know that you are looking forward to a career in software engineering. At the moment, you need to work really hard to secure admission into a good college.
You need to understand the basics of physics, chemistry, mathematics and computers. This will help to increase your board examination percentage. Along with these, you should also solve various model test papers and competitive papers for AIEEE/IIT. Such competitive books are easily available in the market. This will also help you crack the various entrance examinations that you will appear for after passing 12th.
Ensure your percentage in class 12th is over 75 (at least 70). After you are done with your board examination, you should appear for the following entrance examination:
1. IIT JEE and IIT Advanced for admission into IITs.
2. AIEEE for admission into NITs and other government colleges.
3. Individual state examinations (OJEE for Odisha, COMEDK for Karnataka, EAMCET for Andhra Pradesh/Telangana etc.) for admission into private colleges in respective states.
The more the entrance examinations you appear for, the more options for colleges you will have for yourself.
Once you secure your position in a good college, ensure you maintain at least 70 percent throughout with no backlogs to be eligible for placement interviews in most companies.
