BITSAT

Yes, you will get admission in ICFAI University.

The books of Arihant Publication are the best for BITSAT preparation.

Syllabus of IIT JEE and BITS is same but in BITS you have to prepare for English. Also, the level of BITS is higher than that of JEE Mains and 12th board but low in comparison to JEE Advanced. I think you should first focus on JEE Advanced so can you will be able to solve good quality questions and able to clear both BITS as well as JEE Advanced
Best of luck.

No. In BITSAT, class 12th marks are not given any weight-age.
You need to score well in BITSAT to get admission in BITs, Pilani.

Admissions in BITS is made purely on merit. The merit position of the candidate for admission is based on the score obtained by the candidate in the BITSAT. BITS also gives direct admission to first rank students of all the central and state boards to their First degree programme of their choice, irrespective of their BITSAT score.

You have more than enough time. Keep yourself on the right track. Practice as much as you can. Strengthen you weak areas, and get well versed with the syllabus.

Placement have no relationship with the years you drop, but with the skills you have. They want most skilled and hardworking employers for today, no matter what was your history.

I am sorry but you are not eligible for BITSAT, but you are eligible for JEE main and State engineering entrance exam. I will suggest you to prepare for JEE main and JEE advance. These exams are better than BITSAT.
