Want to know more about WB JELET
As per the WB JELET exam pattern 2025, the exam will be conducted offline, using a pen-and-paper format, with a duration of 2 hours. The medium of the exam will be English, and it will consist of multiple-choice questions. There will be a total of 80 questions in Category 1 and 20 questions in Category 2, where one or more options may be correct. For Category 1, 1 mark will be given for every correct answer, with a deduction of ¼ marks for every wrong answer. In Category 2, marking all correct options will yield 2 marks and any combination of answers containing one or more incorrect options will be treated as incorrect and yield zero marks. For partially correct answers, the marks awarded will be calculated using the formula 2 x (no of correct options marked/total number of actually correct options).
Category I: 1 mark is awarded for each correct answer, while ¼ marks will be deducted for each wrong answer. Category II: Marking all correct options will result in 2 marks. Any answer containing one or more incorrect options will be considered incorrect and will result in zero marks. For partially correct answers, where not all correct options are marked and no incorrect options are marked, the marks awarded will be calculated using the formula: 2 x (number of correct options marked/total number of correct options).
The West Bengal Joint Entrance Lateral Engineering Test (WB JELET) is conducted annually by the West Bengal Joint Entrance Examinations Board (WBJEEB) to provide eligible candidates admission into the second year (third semester) of Bachelor's Degree courses across the Engineering/Technology/Pharmacy except for Architecture in the government and private colleges of West Bengal.
The candidate will receive one mark for each correct answer provided in the WB JELET exam. For each incorrect answer, one-quarter of a point will be deducted. There are no marks awarded for unanswered questions. If more than one response is marked in a single question, the question is considered incorrect, and 0.25 marks are deducted.
The very first step to begin the WB JELET 2025 exam preparation is to carefully analyze the WB JELET 2025 syllabus & exam pattern. By analyzing the WB JELET exam pattern and syllabus, candidates will be aware of the topics asked in the WB JELET 2025 exam along with the distribution of marks, mode of exam, duration etc. Candidates must also practice sample question papers and previous year question papers of WB JELET to enhance their preparations.
