It is conducted by the National Testing Agency (NTA) for admission to undergraduate medical courses (MBBS/BDS) in government and private medical colleges across India. NEET assesses a candidate's knowledge in Physics, Chemistry, and Biology (Botany and Zoology) from the Class 11 and 12 syllabus

The exam is usually held once a year, and the result is used for admission to various medical institutes, including AIIMS (prior to 2020) and JIPMER (before 2020, both now included in NEET). It is a highly competitive exam with millions of students appearing for it annually.

The Joint Entrance Examination (JEE) is a national-level entrance exam in India for admission to undergraduate engineering programs, primarily in IITs (Indian Institutes of Technology), NITs (National Institutes of Technology), and other top engineering colleges. It is conducted by the National Testing Agency (NTA) in two stages:

JEE Main: The first stage, which serves as a screening test for JEE Advanced. It evaluates candidates in three subjects: Physics, Chemistry, and Mathematics. JEE Main scores are used for admissions to NITs, IIITs, and other participating institutes. JEE Advanced: The second stage, specifically for admission to IITs. Only candidates who qualify JEE Main are eligible to appear for JEE Advanced. The exam is highly competitive and typically held once or twice a year. It assesses students' understanding and application of concepts in Physics, Chemistry, and Mathematics on the basis of Class 11 and 12 syllabus.

The National Defence Academy (NDA) Exam is a national-level entrance exam in India, conducted by the Union Public Service Commission (UPSC). It is for candidates aspiring to join the Indian Army, Navy, or Air Force as officers through the NDA, located in Pune.

The exam is held twice a year and consists of two parts:

Written Examination: The NDA exam includes two papers: Mathematics (300 marks) General Ability Test (GAT) (600 marks), which includes English, General Knowledge (Physics, Chemistry, General Science, History, Geography, and Current Events). Interview/SSB (Services Selection Board): Candidates who qualify the written exam are called for an interview process that assesses their personality, intelligence, and aptitude for military life. Candidates must be unmarried male/female citizens of India, between the ages of 16.5 and 19.5 years, and have passed or be appearing for their 12th standard exams (with Physics and Mathematics for Navy and Air Force).

The National Aptitude Test in Architecture (NATA) is an entrance exam in India for admission to undergraduate architecture programs (B.Arch) in various institutes across the country. It is conducted by the Council of Architecture (COA), typically twice a year.

NATA assesses candidates' skills in areas like:

Mathematics (General Knowledge in Mathematics) Drawing and Observation Skills (for evaluating creative abilities) Aesthetic Sensitivity (including visualizing 2D and 3D objects and spatial understanding)

Logical Reasoning and Analytical Skills
The exam consists of two parts:

Part A: Computer-based test (CBT) assessing drawing and aesthetic skills.
Part B: A paper-based test (PBT) focusing on multiple-choice questions related to mathematics and general aptitude.
The NATA exam is essential for admission to many private and government-funded architecture colleges, including those that offer the B.Arch program. Candidates must have completed their 12th standard (or equivalent) with Mathematics as a subject.
