FAILED in class 12th from cbse board for 2 times but now I'm preparing for it to secure my 95+% this time..so can I start UPSC preparatio?
Sure dear Ashutosh you can be prepared for UPSC from now but you have to know about the eligibility criteria for UPSC that is - you have a graduation degree from recognised college/university in any stream.
Well prepared for your 12th and simultaneously prepared for UPSC, failure is temporary, do your hard work you can achieve your target by hard work, practise and patience. Be motivated.
All the best dear
Hope that helped.Thank you.
