Hello,

There are some internships which are usually open for students of all fields provided you have the skillets required to perform the work. For example, the content writing internships usually demand good hold of English Language and you can easily get selected if you are fluent in English. Similarly, Data Entry internships also demand 12 passouts with good hold in MS Excel and other data entry softwares.

Also, since your subject is Maths, you can join as subject specific intern in many EdTech startups, where you will get to work on subject related topics and questions.
