Hello Bazaru,

Following is a list of best polytechnic courses after 10th in India -

• Electrical Engineering Diploma
• Diploma in Metallurgy
• Diploma in Instrumentation and Control
• Computer Science and Engineering Diploma
• Aeronautical Engineering Diploma
• Diploma in Fire and Safety Technology
• Diploma in Chemical Engineering
• Agricultural Engineering Diploma
• Diploma in Mining Technology

Though I think it's better to get admission in polytechnic after class 12th only. It will clear your basic knowledge. If you take admission now in polytechnic and later you have a plan for doing B.Tech then you might face some problems. After all, it is your choice. But take your decision wisely.
