JEE

Hello Aishwarya,
First of all, keep your focus in your coming JEE exam. Do your 100% in upcoming exams. Almost all IITs and some NITs have Environmental Engineering. Infact, IIT Bombay, IIT Delhi and IIT Kanpur are better suited to offer world class Environmental Engineering course. Here it is a link for colleges in Delhi and Delhi NCR google it-

Feel free for further queries. Good luck.

To take admission in IIT, you need to qualify JEE Main paper 2 that is for B.Arch. Then, you need to qualify JEE Advance. After that, you will get the chance at JEE Advance AAT i.e. the Architecture Aptitude Test. After you qualify AAT, you will get the seat.

A candidate can appear in both the terms of January and April. The best score will be consider among both the exams. And, after that a common rank list will be issued. For more details visit the Portal good Luck.

FITJEE and Aakash Institute are the best Institutes offering the integrated course in Kolkata.

Since it is in January, you must have gone through your course. So, now for revision stick to NCERT concepts, and solve as many questions and sample papers as possible. Try giving mock tests as well.

You should be specific of which college are you talking about? A rank around 2000-3000 is a very decent rank to get admission in many of the colleges (excluding the top one's like Delhi, Mumbai, Kanpur etc.).

What is your category? It is really difficult, if you are from All Indian Category other than Odisha, because the institute has been added to JOSSA from this year, which means the cutoffs will increase exponentially as compared to previous years.
But, don't lose hope and try in as many colleges as possible.

Hello Rajesh,
Sastra University admits students in two ways: one with a combined score of intermediate and JEE for 75% while the other way is only with intermediate scores which account for 25% percent of seats. So, you have good chances of getting admission at Sastra University with your score in intermediate.

Hi, score of 200-220 marks out of 390 would be needed.
