All I want is the current ratings and standing of this light novel series in Japan.
In terms of light novels, it seems to be the best selling series of 2014. Based on sales surveyed from November 18, 2013 to November 16, 2014, it ranks #1 with an estimated 1,599,614 copies sold.

However, if you look at individual volumes, Mahouka Rettousei no Koukou volume 13 ranked #5 with 226,371 copies sold. In comparison, Kagerou Daze V -the deceiving- ranked #1 and sold 398,038.

Hope that answers your question.
