which is the best non technical polytechnic course after 10th with high salary
Dear Aspirant,
There are almost no course after the level of 10th which provide high salary, even polytechnic highest salary is in the range of 20-30k with latter in the exceptional cases.
You can however, start slow. You can join some computer diploma courses and then try to start building up your career from there on.
Hope this helps. Thank you.
