Students studying in 12th must check the syllabus, curriculum, pattern, and other board exam guidelines.
Every year, lakhs of students appear for the exam, and the board also announces the result for those students. This year, JAC Class 12 results for Science stream were released on June 21, 2022. Furthermore, Class 12 is the final year of higher secondary education in any board exam. Thus, students who succeed in the examinations have the opportunity to continue their studies at colleges and universities.
On November 15, 2000, Jharkhand state was framed after separating its boundaries from Bihar. On February 26, 2003, the Jharkhand State Legislature passed the Jharkhand Academic Council Act 2002, which was signed by the Honorable Governor of the State and announced by the Government on March 4, 2003.
The State’s public education system is governed by the Jharkhand Academic Council, which oversees primary and secondary education in the state. JAC board has links with a variety of schools and institutes, in addition to the state’s other mainboards, such as ICSE and CBSE.

List of Future Exams After JAC Class 12
Competitive examinations have now become an integral part of our educational system. There are a variety of competitive examinations and reward programmes available to students after class 12. These competitive examinations are used to assess a student's mental ability and intelligence quotient, and those who pass are granted scholarships.
Students are mainly aware of the most popular exams after class 12 exams: NEET, JEE, and CLAT. These are national examinations. However, there are several alternative paths that students can follow to begin laying the groundwork for their preferred job.
Joint Entrance Exam (JEE)
The Joint Entrance Test (JEE) is a very well-known national exam taken by all aspiring engineers in India. The JEE is an engineering test that is accepted by numerous colleges around India. After class 12, students from all around the country can take these entrance and competitive exams.
This test qualifies students for admission to famous and prestigious institutes like IITs, NITs, and IIITs. The JEE entrance test, administered by the CBSE, consists of two distinct and separate stages:
National Eligibility cum Entrance Test (NEET)
The NEET is the medical equivalent of the famed JEE engineering examinations. These exams are overseen by the Medical Council of India. It was founded in 1997 under the Graduate Medical Education Regulations.
Currently, the NEET is arranged for two distinct graduate programmes and are as follows:
Common Law Admissions Test (CLAT)
The CLAT entrance test, as the name implies, is for students who want to be lawyers. It assesses their eligibility for admission to several law schools located around the country. CLAT, like the JEE and the NEET, is a nationwide exam.
This law entrance test is carried out for two hours. The CLAT exam paper has 150 multiple-choice questions. It is divided into five sections. Students must answer questions from areas such as follows:
