I think people are being a bit harsh towards 2014newme. According to Wikipedia:
Remedial education (also known as developmental education, basic skills education, compensatory education, preparatory education, and academic upgrading) is assigned to assist students in order to achieve expected competencies in core academic skills such as literacy and numeracy.
Whereas special education is designed specifically for students with special needs, remedial education can be designed for any students, with or without special needs; the defining trait is simply that they have reached a point of underpreparedness, regardless of why. For example, even people of high intelligence can be underprepared if their education was disrupted, for example, by internal displacement during civil disorder or a war.
If the provenance of this article is to be trusted (and there may be valid doubts - I am not endorsing it), 'remedial' would seem not to be so far off the mark.
Of course, Urban Dictionary says that 'remedial' is a synonym for 'stupid'. I doubt 2014newme was aware of that.
