Yes, you can appear for both the compartment and improvement exams in the same year of class 12 CBSE. However, you will have to fulfill the eligibility criteria for both the exams separately. For the compartment exam, you are eligible to appear if you have failed in one or two subjects in the annual board exam. The schedule for the compartment exam is usually released in the month of August by CBSE. For the improvement exam, you are eligible to appear if you have passed in all the subjects in the annual board exam and want to improve your marks in one or more subjects. You can apply for the improvement exam in the year following your class 12 board exams. You can check the CBSE website for more information and the exact eligibility criteria for both the compartment and improvement exams.

According to the CBSE rules, if you fail in 3 out of 5 subjects in your class 12 exams, you will be considered as having failed in the board exams. In this case, you will need to appear for all 5 subjects in the upcoming CBSE compartment exams. However, if you have failed in only 2 subjects and want to apply for improvement in 1 subject, you can apply for both compartment and improvement exams. In this case, you will need to appear for the compartment exams for the subjects in which you have failed and also appear for the improvement exam for the subject you want to improve. It is important to note that the compartment exams are usually conducted within a few weeks after the declaration of the main board exam results, and the exact dates and procedures for applying for the compartment exams may vary depending on the CBSE rules and regulations. I recommend that you visit the official website of CBSE or contact your school/college authorities for more information on the compartment and improvement exams and their application procedures.
