IELTS

You don't have any chance of getting admission in a good college. Stanford's cut-off is 740 and Wharton's is 728.
However, if your aim is just to get MBA at any cost then IIPM, Manav Rachna and Manav Bharti are the kind of institutes which exist in the USA who can't provide you placements, but they badly need students so you can search and apply for such B or C category institutes.

You can use. But, you will not get more marks because of it. Your usage of idioms should be in a very casual way, the examiner should not feel that you are using it deliberately. Natural way of speaking will give you high Mark.

55 backlogs or 55%? It's a huge number if you have had this much number of backlogs, do you even have that much number of papers and if yes, I don't think any good university will readily accept you.

No, you can't. You need at least 6.5 band overall for the same.

You can read English magazines, journals, newspaper, watch English and listen to English songs.

Hi Abhishek,
Universities won't grant you admissions on basis of your IELTS alone. What about your education profile?

Hi Aashish,
You are comparing two very different subjects which have no relation to each other. It is best if you decide if you are inclined more towards hospitality or engineering. If you are strong in mathematics and want a career in engineering you should go for B.Tech. Hotel management is a different field altogether. To be in HM you must have a vibrant personality and business skills as well. Research more on what hotel management is about, the career outcomes, etc. and see if this is what you have been looking for. Both the sectors have good prospects in their own sectors.

Different universities will have different cut-offs. However, most of the universities will accept a score of 7+ in IELTS and 95+ in TOEFL iBT. But, it's better to check the minimum requirement for each university.

Hi,
Yes, you can. You must check admission requirements which will depend on the program and university. For Bachelor degree programs, your IELTS is fine but once again check on university websites.
