In different countries, the score or grade award systems are different. Moreover, it does vary with the universities as well. As far as I know, in India, the universities follow two different grading schemes:
- Absolute grading
- Relative grading
In the absolute grading scheme, the papers are graded as per a predefined range allotted to each grade. For example, A+ grade would follow the range 90-100, A- would follow 80-90, and so on.
In the relative grading scheme, the papers are graded as per the university rules or the faculty in-charge of the course. Usually, they follow a scheme mark distribution where each score is checked against a cut-off, not like the absolute grading scheme. Here the A+ might follow the cut-off as 77 out of 100, if the top score is 82 (example).
In the grade or score card, the CGPA system is mentioned (usually at the back side of the card). So, there would not be any issue with this.
Further, you have not mentioned in your question, which grading scheme your university follows. So, assuming any of the two above, a CGPA of 7 is not that bad to be ashamed of.
Moreover, as mentioned in Scott Seidman's answer, it would be wise to mention explicitly in the application itself.
