Can I get central university of Ajmer? I got 20 marks in CUCET 2017.

You have a good chance to get CURAJ at this rank but if you don't get it, other options include CU Haryana and CU Jammu.

The cutoff marks for B.Sc. (Hons.) courses at Central University of Rajasthan (CU Rajasthan) are determined based on the CUET (Central Universities Entrance Test). For instance, the cutoff for B.Sc. (Hons.) in subjects like Physics, Biochemistry, and Environmental Science ranges from 223 to 351, depending on the course and category. For specific details related to each B.Sc. program, you should refer to the CUET cutoff trends and consider factors like exam difficulty and seat availability.

Central University of Rajasthan offers BTech for a duration of four-years at the UG level. The course is spread across eight semesters. CURAJ offers BTech in the below specialisations:

• Computer Science Engineering
• Electronics and Communication Engineering 
• Biomedical Engineering

CURAJ is a central university and like all central universities, it does not release a cut off for the general public these days especially after introduction of CUET. So the cut off score will only be known by someone who took admission.

I would suggest you try connecting with people who have been pass out or are pursuing the course to know the exact details and not trust online random information as it may be wrong. 

Score of 307 is not enough to get you to Central University of Rajasthan. Last year cutoff for General category was 374.1 marks for

integrated B.Sc M.Sc Biotechnology at Central University of Rajasthan . This year it may get lower down but still you have to work hard more or you can go for other universities.
