For admission in diploma programs and the UG degree leading to the B.Tech and the B.Sc degree courses, the candidate must have passed the plus two examinations/12th class/10+2 with the minimum of 50% with science subjects out of chemistry, mathematics, physics, biology, home science.
The students from the different domain in education degree in the UG programme such as the UG in hotel management, B.Sc with life science or the UG in home science may get the admission in PG degree courses in the field of food technology.
Many of Indian colleges or the universities have marked the criterion of entrance examination before the admission in any of the above programmes. Some of the entrance examinations includes the following, which are conducted by the various universities in India:
JEEP (Joint Entrance Examination Polytechnic)
CFTRI (Central Food Technological Research Institute Entrance Examination)
IICPT (Indian Institute of Crop Processing Technology Entrance Examination)
GATE (Graduate Aptitude Test Examination)
For admission in diploma courses leading to the polytechnic diploma, the candidates must have to appear in JEEP entrance examination, and for admission to UG programme, the candidates must have to appear in JEE Main entrance examination. Some of the universities conduct their own entrance examinations.
The admission is based on the minimum 50% marks in the qualifying examination and the score in the entrance examination, followed by the counseling and personal interview.
For admission to PG programs, the students need to attain the GATE entrance examination after the completion of UG degree in the same or related field.

Bachelor of Architecture: Eligibility
The duration of the course is 5 years and to get admission into B.Arch. the student must be fulfilled the following conditions:
10+2 or equivalent with minimum 50% marks along with compulsory subject of mathematics.
10th + 3 years diploma in any stream from a recognized university/ board/ institution.

Bachelor of Architecture: Admission Process
Candidates can take admission in this course through NATA entrance test and to clear the exam the candidates should have understanding of subjects. Every college or institute has different criteria for admission and moreover state or region have the another impact on admission.

Eligibility for B.Tech Robotics Engineering
The candidate applying for the course must complete 10+2/equivalent examination with minimum 55% aggregate in PCM/PCB. The candidates who have completed a diploma in robotics technology or automation technology can also apply for this course through lateral entry. Along with these requirements the candidates are to appear for entrance examinations to get admitted into robotics engineering course.
Admission process for B.Tech Robotics Engineering:
The admission processes vary from institute to institute and/or state to state. Most of the colleges require the candidate to qualify an entrance examination to get admission in B.Tech Robotics Engineering. Candidates who are currently appearing or have completed 10+2 or equivalent examination are eligible to appear for these entrance examinations.
IIT JEE Mains
JEE Main is an all India common engineering entrance examination of the objective pattern which is led for admission in engineering colleges and courses all over the country. It is thought of as one of the most challenging engineering admission tests. JEE main score is used by almost all the engineering colleges across India. IITJEE mains entrance examination for B.Tech and B.E. (Paper I) has an objective type questions with equal weightage to Mathematics, Chemistry and Physics.
SRM University Joint Engineering Entrance Exam: This Entrance Exam is conducted to offer admission into various Undergraduate courses. SRMJEEE is University level examination conducted to offer may engineering courses across four campuses of SRM University. SRM University conducts both Offline and Online exams. SRM University also provides scholarships for the top scorers of SRMJEEE.
Direct admissions:
Direct admission through management quota is offered by almost all the colleges. Government engineering colleges do not offer direct admission due to absence of management quota.

Eligibility for B.Sc. In Nutrition and Dietetics
The basic minimum eligibility for pursuing B.Sc. in Nutrition and Dietetics is a X and XII qualification from a recognized educational Board with Physics, Chemistry and Biology as the main subjects at the intermediate level, with a minimum aggregate score of 50%.
Some universities/ colleges also accept Botany/ Zoology/ Computer Science/ Biochemistry instead of Biology as one of the main subjects studied in class XII.
B.Sc. In Nutrition and Dietetics: Admission Process
Admission to the course at some colleges and institutes offering B.Sc. in Nutrition and Dietetics is based on the candidates performance in the relevant entrance examination conducted by the concerned university.
Admission to the course at some other colleges/ institutes, however, is based on the candidates scores in the qualifying exam, i.e. classes X and XII. Subsequently, a merit list is prepared, based on which seats are allotted to the shortlisted candidates.
