CBSE Class 12 Preparation Tips for Computer Science
Preparing for the CBSE 12th board examination correctly and effectively can fetch you the desired outcome. Most of the time, students commit some silly mistakes while preparing for the board examinations that lower their aggregate scores. Refer to the CBSE Class 12 Computer Science preparation tips given below:
1. Know the CBSE Class 12th Computer Science Syllabus
A student must go through the CBSE Class 12th syllabus for computer science before starting to prepare for the exam. The syllabus would also tell you the topics with a higher weightage of marks, which can not be skipped or avoided. It would also help the students in forming a proper study plan for the exam.
2. Exam Pattern and Types of Questions Asked
Once the student gets to know about the syllabus, they also get an idea about the CBSE Class 12 exam pattern, marking scheme, and type of questions being asked year-round. Knowing the same will help to set the priority of chapters during the CBSE Class 12 Preparation for Computer Science. Check some important points related to the exam pattern and marking scheme before moving ahead. Below are some quick CBSE class 12 preparation tips for the computer science paper-
Students should solve all the questions within the given time.
There will be no deduction of marks for providing an incorrect answer, hence, students should try to attempt all questions.
Highlight the important sections either by underlining or by using a different colour pen, other than Red.
3. Make CBSE Class 12 Time Table for Computer Science
After collecting all the details of the exam pattern, syllabus, and mark distribution, students have to divide their daily schedule in such a manner that they cover all the topics and chapters before December. Students should strictly follow their study schedule to cover the complete syllabus on time. It is necessary to prepare the CBSE 12th board syllabus before December, as most of the schools conduct the pre-board examination in December/January to check the performance of students. Hence, make a daily study schedule where you devote equal time to all five subjects. Additionally, give more time to tough topics and prepare them on a priority basis, as they consume more time in comparison to other topics.
4. Create Short Notes or Flashcards
Along with preparing a topic, students are advised to make handwritten short notes or flashcards of important facts. Writing these notes helps students to memorize the concept faster. Besides, these short notes make the revision process easier as students do not need to carry heavy books all the time.
5. Revise Important Facts Regularly
The human brain is very complex. It tends to forget things on the D-day. Hence, students should put extra effort into retaining all the information studied. It is advised to keep practising programming and coding regularly to get the hang of it. Short notes will help make your revision process faster. With the help of the same, students can revise the important sections on the go.
6. Solve CBSE 12th Computer Science Question Papers
Practicing previous year CBSE 12th question papers is a must to score good marks in computer science exams. Moreover, you get to know about the question trend. Solving a minimum of 5-6 questions of each type from previous CBSE 12th board papers helps in clearing all doubts. Students can take the help of their teachers to clear the concepts as well.

Changing from the CBSE board to the Odisha CHSE in Class 12 is generally difficult and often not ideal due to differences in syllabi and examination structures. Most boards, including Odisha CHSE , do not recommend switching in the final year of schooling. It is crucial to consult both CBSE and Odisha CHSE authorities for specific policies, but making such a change earlier is advisable to prevent academic complications.

Hello there! Thanks for reaching out to us at Careers360.
Ah, you're looking for CBSE quarterly question papers for mathematics, right? Those can be super helpful for exam prep.
Unfortunately, CBSE doesn't officially release quarterly papers - they mainly put out sample papers and previous years' board exam papers. But don't worry, there are still some good options to help you practice!
Have you checked out the CBSE sample papers on their official website? Those are usually pretty close to the actual exam format. You could also look into previous years' board exam papers - they're great for getting a feel for the types of questions that might come up.
If you're after more practice material, some textbook publishers release their own mock papers which can be useful too.
Let me know if you need any other tips for your math prep. Good luck with your studies!
