It's extremely competitive at the national level, your scores are far from anything to be ashamed of.
I graduated my engineering undergrad top of my class with only 3 As after first year, the rest A+, and only have received A+ in all graduate courses I've taken. I was given an 8 for academic excellence, meaning lots of rooms for improvement in this category and many nominations above me. Obviously there is more to academic excellence than grades alone, but this gives a sense of the competitiveness we're dealing with.
