IIT

Hello Pani,
The fee in different IIT's is different and we're not raised for many years. These days, almost all IITs have enhanced their fees. In IIT, Mumbai it is approximately Rs. 65k per semester.

You can surely try this year for IIT-JEE Mains. For clearing Advanced you need to have 75% in class 12th or to be in the top 20 percentile. You can take a drop of 1 year, but you need to be very dedicated and committed towards preparation. Constant tests will give you an idea about your performance.

Dear Biswajeet,
No, it's not a good choice to do M.Tech in steel technology. After doing this course, there will be limited opportunities. You should choose either thermal engineering, design stream, manufacturing or precision engineering stream. There is more demand of this. Otherwise, choice is yours.

Hello Adarsh,
Yes, you are eligible to take admission in IIT after completion of the diploma. The diploma is considered as equivalent to 12th and hence you can get admission provided you fulfil all other conditions.

MCA is offered at IIT Roorkee only. The admission to the course is done on the basis of an entrance exam IIT-JAM which is conducted by IITs for admission in post graduate degrees in Science subjects.
