Hii tell me one thing doing polytechnic in computer science or any other trade after class 12th then complete my diploma can I get admission in btech in aerospace engineering or aeronautical engineering because I want to become an astronomy but my financial condition is not too good plz suggest me ?

Hello,

Pursuing diploma after class 12 is not a good option as this will will waste your 2 years of class 11 and 12. Diploma is a good option only after 10th. Now, i would like to suggest you to follow this following path. Take science in class 11th and 12th try to get very good marks, then appear for Engineering entrance exams like JEE mains and try to get a good rank in JEE mains examination.Then you can appear for JEE advance and can secure admission in IITs.
Aerospace engineering or aeronautical engineering is a very high specialization course and you need a very good college if you want to do well in future and for that IIT is the best place to study. So, study very hard in class 11 and 12 prepare well for JEE mains and advanced. As far as your financial condition is concerned then let me tell you, if you can get into any of the IITs then there will be many banks who will be ready to give you student loan easily and since you will be in IITs, you will easily get very good placement and package. So, don't worry about money and just prepare well and try to get into any IIT and that should be your first and foremost motive. Best colleges for Aerospace/Aeronautical engineering:

• IIT Bombay
• IIT Madras
• IIT Karagpur
• IIT Kanpur
• IIST Tiruvanatapuram

I hope this helps.
