Is the youth of India confident or confused? Why?

They are more confused than ever.

It starts with their basic education system. They take science as their major in their HSE and then they opt for engineering. They make out those 4 years anyhow by bitching about the courses, teachers and being cynical about their future and placements. They make it to their job and then they leave it in 4 months, 7 months or in 1 year, likewise. They give every possible entrance exams possible in this stage. From SSC to Bank PO. From CAT to RBI Assistant. From GATE to Analytics( if he/she has got a core job placement) Its not that they want to pursue certain job or stream. The major motivation for them is that they just want to leave their company as soon as possible. They make it to any management college and after 2 years, they settle for a job. They again leave their jobs in similar short month fashion and then they want to pursue UPSC. It is not they want to get into civil services or they want to serve the nation. They just want to leave their current job somehow. They feel like they are not making an impact in the organisation. They feel that I was studied so much and I have ended up entering data in Excel Sheets. After that, they even found a startup but shut it down in an year or alike. This cycle continues till one gets married. After marriage, responsibilities and family pressure don’t let you leave your stuffs anytime soon. You somehow get patient and then you dress up daily for the job you hate and meet the persons that you don’t wanna meet. It’s pathetic but true. I can’t tar every wall with the same brush but I just tried to portray a chunk of population. No offence.

Hope it helps.

Can I clear IIT in preparation of 100 days?

Let's be blunt and precise.

You have 100 days in your hand. Give 10 hrs for self study each and every day. Revise stuffs after every 2–3 days. Give atleast 2–3 mocks in a week. Analyse thoroughly. Note down your areas of strength and weakness. Also 10 hours mean “Raw 10 hours”. You need to have a timer set and then you should count your hours.

In the end you would have done 1000 hrs of self study. That's more than enough to get you through advanced. Though decent ranking and dream colleges may still be a distant affair but it's better to take a chance and miss without aiming at all.

Hope it helps.

Thanks.
