There is no clear demarcations as such.
Feel free to use your discretion and put them under appropriate heads.
You may use definitions on en.wikipedia.org for reference and decide.
As far as i know allocation of heads if inappropriate might not create any issue.

Best of luck for your preparation.

As the percentages are clearly stated with the CGPA, its better to write percentages! I think conversion certificate shall not be a necessity since its purpose is to convert CGPA to percentages and it is already done in your marksheet.

Kindly get further clarifications by contact the admissions office for the same at the earliest. (contact details mentioned in the call letter sent to you) They would guide you about the same as they already calculated your scores in profile rating while giving interview calls.

About attestation, college/school authorities/bank managers/government gazetted officers can attest your marksheets. Also, self attestation is sufficient too. Only your marksheets and degree certificates (if you have any, only for those who have completed graduation) need to be attested.

keep the originals in a dockette along with your other certificates. Its advisable to carry atleast 2 sets of attested copies of your marksheets and IIM-A takes one set (as far as i remember) just in case if it might be asked.

Hope this helps.

This is with regard to the application form. In the form, we are to write “curricular”, “co-curricular” and “extra-curricular” activities. Now, a under 100 JEE rank would count as curricular or a co-curricular? And what is the difference between co-curricular and extra-curricular? Is there anything else apart from research papers published that we can add to co-curricular?

Since you are going to pursue a “post graduation” in a particular sector, it is important that you are making a well-informed choice. Hence, the question why ABM is the core question with the interview.

The ABM program is for people interested in agribusiness, rural and allied sectors and work in the same in the future. Going through IIM-Ahmedabad website gives you a fair idea about the course. It is advisable that you browse the internet about agribusiness sector in India and abroad to make a more informed choice. Think about your future plans and see how they align with the ABM program. Perhaps, it can help you to understand why ABM. The genuinity for the program shall naturally evolve within you when you realize your true interest in pursuing ABM.

Hope this helps.
All the best for preparation.

Also it is important that you state your own reasons for pursuing the ABM programme and not why the ABM programme has be part of IIM A.

The interview would concentrate more on your overall understanding of the subjects studied during engineering. It does not necessarily involve questions pertaining to a particular subject.
Have a broad overview of applications and the latest happenings in your stream of graduation and it will help you a lot in facing the interviewers.
Best of luck for your interview.

Kindly contact the admissions office for the same at the earliest. (contact details mentioned in the call letter sent to you) They would guide you about the same.
Since as you mentioned that you need to travel a lot, kindly ask the office for the same that whether they shall accept if you can get it scanned and receive via email/fax. Hope this helps.

Best of luck for your preparation.

My uni gives a CGPA out of 10, do I need to take a conversion certificate (I will have to travel really far for that), or is *10 sufficient? Thanks..
