RRB ALP CBT 1 Answer Key Objection Process

The Railway Recruitment Board first releases a provisional answer key so that candidates can check their answers. If a candidate finds any mistake in the question, option, or answer key, he or she can raise an objection through the official website. This step is very important because the final result is prepared only after all objections are reviewed.

Candidates must log in using their registration details and select the question they want to challenge. Proper proof must be uploaded to support the objection. The board will carefully review all objections and prepare the final answer key. After this, the answer sheets will be re-evaluated, and the results will be declared. This process ensures the result is fair for all candidates.

RRB ALP Answer Key 2026 Marking Scheme

The marking scheme of the RRB ALP CBT 1 exam is simple. Candidates get 1 mark for each correct answer and 1/3 mark for each wrong answer. No marks are deducted for questions that are not attempted. Candidates should follow this rule while checking the answer key.

Many candidates forget about negative marking and end up with incorrect scores. Therefore, it is important to count both correct and incorrect answers carefully. The correct calculation will help candidates know their expected marks and understand their chances of qualifying for CBT 2.

• Correct answer: +1 mark
• Wrong answer: −1/3 mark
• Unanswered: 0 mark
• Total questions: 75
• Total marks: 75

How to Calculate Scores Using the RRB ALP CBT 1 Answer Key?

Candidates can calculate their expected marks by using the response sheet and the official answer key. This helps gauge performance before the result is announced. The calculated score is only tentative, but it gives a good idea about qualification chances.

To calculate marks, count correct and incorrect answers, and apply the marking rule. After subtracting negative marks, the final number will be the estimated score. Candidates should also remember that the final marks will be based on the final answer key.

Steps to calculate the score

1. Download the answer key and response sheet
2. Count correct answers
3. Count wrong answers
4. Multiply correct answers by 1
5. Multiply wrong answers by 1/3
6. Subtract negative marks

Formula

Score = Correct × 1 − Wrong × 1/3

RRB ALP Minimum Qualifying Marks

The minimum qualifying marks are the lowest marks required to stay in the selection process. These marks are fixed by the Railway Recruitment Board for different categories. Candidates must score at least the minimum marks; they will not be considered for the next stage.

However, getting minimum qualifying marks does not guarantee selection. The actual cut-off may be higher depending on exam difficulty and the number of candidates. So candidates should aim for higher marks while checking the answer key.

• OBC – 30%
• SC – 30%
• ST – 25%
