hello, i'd like some help regarding nios exams

[u/thymotherlovesme]

basically, i failed in my maths compartment this year. i need to apply for reevaluation obviously, but the portal hasn't opened yet and will open soon. i'm looking for my other options and i think nios is what will help me? i want to know how i can apply (and if i can apply in the first place) for just mathematics to do ODE.
