RRB ALP CBT-1 Exam Pattern & Marking Scheme
The RRB ALP (Assistant Loco Pilot) & Technician Grade III recruitment is conducted in two CBT stages. The CBT-1 is the qualifying stage that determines shortlisting for CBT-2. Unlike other RRB exams that have 100 questions, the ALP CBT-1 has only 75 questions carrying 75 marks.
The ALP CBT-1 carries 1/3 negative marking for wrong answers. With 75 questions in 60 minutes, candidates get 48 seconds per question. Since multiple shifts are conducted, RRB applies percentile-based normalization to equalize scores across different question papers.
ALP Selection Process & Eligibility
The ALP recruitment follows a multi-stage selection process. Candidates must hold a 10th pass certificate plus an ITI/diploma in the relevant trade or a degree in engineering to be eligible. The selection stages are as follows.
75 questions, 60 minutes. Covers Mathematics, General Intelligence & Reasoning, General Science, and General Awareness. Used purely for shortlisting — CBT-1 marks do not count in final merit.
Part A (100 marks, common) + Part B (75 marks, trade-specific). Part A covers the same subjects as CBT-1 in greater depth, while Part B tests trade-specific knowledge. Final merit is based on normalized Part A + Part B marks.
Candidates shortlisted for ALP post take a Computer-Based Aptitude Test (CBAT) assessing cognitive abilities. Those qualifying CBAT proceed to document verification and medical examination. Technician Grade III posts skip CBAT.
How ALP Normalization Works
RRB ALP CBT-1 is conducted across multiple shifts with different question papers. To ensure fair comparison, the Railway Recruitment Boards apply a percentile-based normalization method approved by the Ministry of Railways.
Step 1: Percentile Calculation
Your percentile = (candidates who scored equal to or less than you in your shift ÷ total candidates in your shift) × 100. Calculated to 5 decimal places.
Step 2: Base Shift Selection
The shift with the highest mean marks and at least 70% of average attendance is selected as the base shift. Ties are broken by highest individual score, then highest attendance.
Step 3: Linear Interpolation
Your percentile is mapped to the base shift’s score distribution. Since ALP has 75 marks (not 100), the normalized marks will be on a 75-mark scale. This ensures candidates from easier or harder shifts are compared fairly.
Understanding Your ALP Scorecard
After uploading your ALP Response Sheet PDF, the calculator generates a detailed scorecard. Here is what each metric means for the ALP exam specifically.
Raw Marks (out of 75) — Total score = (correct × 1) − (wrong × 0.333). With 75 questions, maximum raw score is 75 and minimum is −25. A score of 50+ out of 75 is considered strong for ALP.
Percentile Score — Your standing relative to other candidates in the same shift. A percentile of 90 means you scored higher than 90% of candidates who appeared in your particular shift.
Normalized Marks — The equalized score used for CBT-2 shortlisting. Since CBT-1 is only for screening, your normalized marks determine whether you clear the CBT-1 cutoff and proceed to CBT-2.
Predicted Rank — Your estimated position among all ALP candidates who checked marks using this tool. Includes overall, zone-wise, and category-wise breakdowns.
ALP CBT-1 Expected Cutoff Range
RRB ALP cutoff varies by zone and category. Below is the approximate expected range based on previous ALP recruitment cycles. These are normalized marks out of 75.
Note: Actual cutoffs depend on vacancies, total applicants, and difficulty of the specific ALP cycle. Use the calculator above to check where you stand.
