Yes, according to your rank, there are chances for you to get admission in SASTRA University. The cut off for CSE are different every year. So you have to wait for the results to come out. 

As far as I know, It's true that you can get a seat at 8 lakh but you can't take that risk because you are also loosing hope for 3rd tier colleges, now  better look for private colleges.

As you have mentioned you have secured 90 marks in JEE advanced 2021 so let me tell your rank would be above 10k so in this rank you can expect lower IITs like Patna, Bhilai, Mandi and other parallel ones.

Yes, you have got a decent rank but it would not be sufficient to fetch you an integrated M. Tech seat in software engineering under category 1 at Vellore campus of VIT.

Both JECRC University-Jaipur and Jagannath University-Jaipur offer BTech CSE courses. However, I cannot say which one is better as it depends on various factors such as course curriculum, faculty, facilities, placements, etc. You can compare the two universities based on these factors and choose the one that suits you best.Although in terms of exposer and infrastructure JECRC university is better than JECRC college and faculty is more experienced in JECRC university. Both are the part of JECRC foundation and thus both are good in terms of placements. 

With a rank of 32,458 in WBJEE 2023 and an SC rank of 2,861, you have a good chance of getting admission in government colleges for CSE or IT in West Bengal.

Few colleges I would gives names of which you can check:-

1. Jadavpur University

2. Maulana Abul Kalam Azad University of Technology (MAKAUT)

3. Kalyani Government Engineering College, Kalyani,

4. Government College of Engineering and Ceramic Technology, Kolkata,

5. University Institute of Technology, Burdwan University,

A correct approach accompanied by a well-built preparation strategy is everything a student needs to ace JEE Main 2023. A last-minute preparation tips for the exam is mentioned below:

• Choose your reference books wisely

According to my perspective, understand but you know In general, to be eligible for UGEAC, candidates should have passed the 10+2 examination or its equivalent with a minimum qualifying percentage in the PCM subjects. The minimum qualifying percentage is typically higher than 59 percentile in JEE Mains.Having a compartment in the math subject of your class 12 examinations may affect your eligibility for admission to engineering courses.I hope you find a path
