The Central Board of Secondary Education (CBSE) has released the 2019 board exam date sheet on its official website - - on Sunday, December 23. The CBSE Class 12 board exam 2019 will begin from February 15 and will conclude on April 3. The CBSE Class 10 board exam 2019 will be held from February 21 to March 29.
The CBSE Class 10 and Class 12 Board Exam date sheet was released on Sunday, December 23, on the official website of the Board. The students can visit the official website of the Board to check and download their board exam date sheet.


The CBSE Board has released the 2019 board exam date sheet seven weeks before the exam date so that students can get enough time for planning and preparation of the papers.

While preparing the date sheet, the Board has also made sure that Board exam dates doesn't coincide with the dates of competitive exams. Last year, the exam date of Class 12 Physics paper had to be reschedule as it was clashing with JEE Main entrance exam date.

The CBSE Board will conduct 2019 board exams in morning session i.e. from 10.30 AM to 1.30 PM. The students will receive answer books at 10.00 AM and question paper will be distributed at 10.15 AM

The Board offers 40 vocational subjects in Class XII and 15 in Class X. The Board offers 240 subjects in total, out of which, this year Class 10 and 12 students have opted for 30,000 combinations of subjects.

The CBSE board exam results 2019 is likely to be released by the first week of June.

CBSE Class 12 Exam

The Class 12 examination of CBSE board is very competitive. The 12th standard examination will begin in March 2019 and will end in April 2019. The board will release the admit card the exam and students can download it by visiting the official website. The CBSE 2019 Admit Card will contain important details like roll number, exam center, etc.

The class 12 results will be declared in the month of May – June (tentative). In 2018 the 12th standard results were declared on 26th May 2018. Candidates who will be appearing in the 12th standard exam must work hard with dedication to succeed in the exam. They must be committed to 2 years of hard work to master the basics for the Class 12 board exam.


Students studying in CBSE board are assessed in two areas: Co-scholastic and Scholastic. The academic year of the Scholastic areas is divided into two terms which are Term 1 and Term 2 and two types of tests which are Formative Assessment and Summative Assessment are conducted to evaluate the academic subjects.

   Formative Assessment: In the primary classes, the formative assessment tests are in the form of oral tests, dictation, homework, class test, projects & assignments, storytelling, elocution, memory test, quiz, etc.

   Summative Assessment: Here students are tested internally. The Summative Assessment (SA) tests are in the form of pen and paper. The tests are conducted by the school. The Summative Assessment is conducted at the end of each term two times each year.

STUDY MATERIALS ARE PROVIDED free of cost to students who have enrolled in our programs

Our faculty of highly qualified teachers and researchers have combed through several books and journals, having collected and processed all the information so that it becomes easily accessible to the student. The study material is prepared in a time tested fashion with the student kept in mind in such a fashion that the student can catch up on the various topics in the event of missed lectures. Besides the theory being extensively discussed, an enormous collection of problems has been added so that the student can learn to apply the concepts over a diverse spectrum of difficulty. All the problems have been worked out thoroughly so that in case the student gets stuck, we've got you covered !
