One of my friends studying at CMR said it is better to opt for CMR University or Christ University, rather than Presidency University. Mainly due to the excessive strict rules of the latter. Being a student of the Presidency, let me share why it is not apt for you.

• At the Presidency, there are a lot of rules that students need to strictly follow. 
• There are no holidays for preparation before exams. The institute believes in classroom study only.
• Out of an entire batch of over 5000 students, hardly 50-60 students get the chance to participate in sports events.
• Fee submission is hectic. Only 2 or 3 counters are available. 
• Attendance should also be maintained.
• They have a strong and cooperative faculty.

Therefore, for normal category students, CMR University and Christ University are better choices. The Presidency has a decent educational background.

Having friends studying in both colleges makes me able to answer your question. Both colleges have convincing reasons and have been in existence for the longest time. 

Christ University offers excellent engineering programs and a highly qualified faculty. They also have an excellent campus. However, based on their online reputation, students are dissatisfied with the programs. 

Presidency University, Bangalore, has an advantage in this regard. The former students have nothing but positive things to say about the faculty. They are cooperative and helpful. The curriculum is always completed on time, giving students enough time to prepare for exams and assignments. It also has some of the best classrooms in the country, all of which are equipped with digital technology for enhanced learning. 

Hence, Presidency University is superior to Christ University Faculty of Engineering for B.Tech.
