Exam pattern : Class 12 Biology syllabus download pdf

  1. Theory Exam:

The theory exam is usually divided into sections covering different units or topics from the syllabus.

Questions can be of various types, including multiple-choice questions (MCQs), short answer questions (SAQs), long answer questions (LAQs), and very long answer questions (VLAQs).

Marks distribution among sections may vary, with some sections carrying more weight than others.

Typically, the exam duration for the theory paper is around 3 hours.

2) Practical Exam:

The practical exam assesses your ability to perform experiments, make observations, and draw conclusions.

Practical exams may include experiments from various topics covered in the syllabus.

You might be required to submit a record of your practical work, which includes observations, results, and interpretations.

Practical exams are often conducted in a laboratory setting under the supervision of a teacher or examiner.

3) Internal Assessment:

Internal assessment may contribute to a portion of your overall grade.

It can include activities such as laboratory work, project work, assignments, and class participation.

The weightage of internal assessment may vary depending on the educational board or institution.

4) Marking Scheme:

Each question in the theory exam is usually assigned a specific number of marks.

The marking scheme may vary for different types of questions (MCQs, SAQs, LAQs, VLAQs).

In practical exams, marks are awarded based on your performance in conducting experiments, recording observations accurately, and analyzing data.

5) Practical File Submission:

You may be required to maintain a practical file throughout the academic year, documenting the experiments performed, observations made, and conclusions drawn.

The practical file is usually submitted for assessment along with the practical exam.
