IELTS

Hi Shashank
General IELTS is required for immigration purposes. Academic IELTS as the name suggests is required for higher studies and admission purposes. See here:

Hi Manav,
Your admissions will not be done only upon your IELTS score. You must have more than 75% if you want a good university. Please mention your education profile and scores for a better answer.

Dear Daksh,
IELTS has two major parts: academic and general. IELTS general is required for job purposes, you can check more about it on IELTS.org. Please remember that IELTS alone will not lead to a job.

Dear Shashank,
Easy or tough will depend on your own competency. Suggestion from me would be that you should check the formats and test pattern. Many people will be having their own opinion about it so it's up to you to judge.

You can not apply in foreign universities after 3 years graduation degree if eligibility requirement is of four years duration degree course. To circumvent this problem, you are advised to do one year PG diploma. With 3 years degree and one year PG Diploma, you will become eligible to seek admission in foreign university which has 10+2+4 education requirements.

You are eligible to appear for IELTS after you attain the age of 16 if you are planning to study in UK, Australia, Canada, New Zealand and US.

Why not try studying the basics and join any good institutes and practice well over questions.

Hi Ravi,
Yes, it is possible but without IELTS chances could be less. Check with the universities if you can enroll into a bridge course in English. International students must meet English language requirements and it is mandatory. You must also meet the admission requirements which are different with different universities. Fiji is also not a very popular study abroad destination so you have to check the university websites for details.
