No. Not at all my friend.

As per my advice, look out for your present scenario whether you can make it or not in next year. Ask yourself if this question. Consult with yournparents and if you want to go for long term then go for it and if you don't apply for JoSaa counselling for admissions in Engineering colleges.

No, JEE is way too hard in comparison with the igrua written test. It's like appearing for a high school class text and appearing for your the weakest subject board exam and that too from ICSE board. And yes, you are a CBSE student. The example gone too far but it's something like that.

Almost impossible in spot round also.

For a general category outside Delhi candidate, its impossible except in spot round which is again a game of luck.

Yes, that is a mandatory thing!
