Minimum percentage requirement for a specific course is 55 and i got 55 percent marks and 7 bands overall ..can i recieve offer letter?

If you have already met the percentage requirement, then that is definitely a good thing. Even your IELTS Score is decent. I am stating it as decent because the score requirement varies across courses, schools and countries and while some may accept an IELTS score as low as 6.5, others might need a 7.5. 

Here what you need to consider is that there are various other aspects of a candidate’s profile that the Adcoms look for and apart from having a good IELTS score and the required bachelor’s GPA, you need to fulfill all those requirements if you wish to get an admit. 

The other important aspects of your profile that should be exceptional are:

1. GMAT/GRE Score

2. Extracurricullars

3. Work Experience

4. SOPs and LORs

All these things will contribute towards an overall holistic profile and make sure you shine amongst the thousands of other applicants. If you are still not sure about your profile or need any assistance for applying to universities abroad, I suggest you directly get in touch with Study Abroad Experts here. They will analyse your profile and not just help you with all the required information but also assist you in the entire application process for FREE.

Hope this helps!
