B.Tech in Australia

Yes, you can do your B.Tech from Australia after completing your Diploma from India.

Today, Singapore is the leading country in the engineering field.
NUS and NTU are the best options in Singapore.

Australia is awesome in terms of education, and duration is 3 years rather than 4 years. To gain entry into an Australian undergraduate course, you need to have class 12th passing certificate. Almost all programmes require a score of IELTS exam, which must not have been taken 24 months before the day of the application and should be more recent. Students should have a minimum IELTS score of 6 and at least 60 in class 12th board exam. Scholarships are available to Indian students.

Very good. Canada is heaven for Indian students. But Ozz is a bit volatile towards Indians.

Hello Sagar,
Typically, the fee structure could be between AU$15000-AU$35000 a year.

Hello Sagar,
Scholarships abroad are almost always based on academics. The only way you can think of getting scholarship is by scoring very well here.

Dear Madhukar,
All foreign countries allow attitude the to take up part time jobs alongside studies including Australia.

Hello Madhukar,
Admissions to undergraduate courses in Australia are not based on any entrance exam but are based on marks obtained in your 12th. I would however advise you to take help from a specialist agency dealing in admissions to Australian universities as they would know all the required nuances.

Hello Madhukar,
Of course, yes. It's good idea surely. The criteria are a bit different but these days many countries are soliciting students for their undergraduate programmes. I would advise you to approach a specialist agency since there are nuances in whole process and you should not falter at any step.
Best wishes.
