1. Memory Test
📊 21 Questions ⏲️ 6 min (3+3)
Memorize figure–number pairs (3 min study) → recall correct number for each figure (3 min). Tests visual recall for signals.
🔹 Sample: Study: 🟢=42, 🔵=17, 🟠=89.
➡️ Q: 🟢 appears with which number? A) 42 ✅ B) 17
⭐ High weightage in ALP
➡️
2. Following Directions
📊 20 Questions ⏲️ 5 min
Navigate letter/number grid using step‑by‑step instructions (“start row2 col4, move left 2, up 1”). Rule‑following under pressure.
📍 Example: Grid 3x4, Start at B2 → move down 2 → left 1 → select letter.
Answer: G
⚡ ~15 sec per question

3. Depth Perception
📊 20-25 Questions ⏲️ 5 min
Count total cubes / bricks including hidden ones in 3D stacked figures. Spatial judgment for loco pilot view.
🧩 3D cube stack: top view + side view → how many total cubes?
✅ Hidden cubes counting practice
👁️ critical for train operation
🎯
4. Concentration Test
📊 96 Questions ⏲️ 5 min
Find specific digit (6 or 9) among rows of digits. Sustain attention and ignore distractors.
🔢 "How many times digit '6' appears in given row?"
Example: 6 9 3 6 2 8 → count = 2
⚡ extreme speed ~3 sec/question
🟡
5. Perceptual Speed
📊 96 Questions ⏲️ 5 min
Hexagonal figure matching: one target, five similar options – only ONE exactly matches.
🟢 Hexagon test: Identify identical shape from A,B,C,D,E. Small rotation or extra line makes it wrong.
🔁 most scoring with practice
⚠️ ALP Qualifying Criteria (No relaxation ANY category)
✅ Minimum T-Score ≥ 42 in EACH of the five batteries – Memory, Following Directions, Depth Perception, Concentration, Perceptual Speed.
❌ No relaxation for SC/ST/OBC/EWS/PwBD – all candidates must pass each battery.
🚫 Failure in any one test battery → Disqualification from ALP post.
📈 T-Score 42 ≈ roughly 35–40% accuracy but varies with difficulty; aim 55%+ for safety.
🔹 T-Score 42+ per battery
🔹 5/5 batteries must qualify
🔹 No negative marks attempt all
🖼️
Figure Position Memory
Memorize positions of figures on grid – recall later. Builds spatial memory for railway signals & track layout.
⏰
Watch Table / Clock Test
Following directions on clock face – crucial for shift timing and attention to detail.
🧱
Hidden Bricks Test
Advanced depth perception – count touching bricks in complex stacks (RDSO pattern).
🔢
Digit Search (6/9)
Rapid scanning among random digits – builds concentration for locomotive cabin environment.
🏆 Coaching Tips for ALP Psycho Test Success
🔹 Battery‑wise mastery: Each battery needs 42+ T‑score; identify weak areas early using mocks.
⏱️ Speed drills: Concentration & perceptual speed require 2–3 sec per question. Daily 10‑min rapid fire.
🧠 Memory bootcamp: 3‑min study + 3‑min recall. Practice figure‑number pairs every session.
🎯 Depth perception: Use physical blocks / 3D software to visualise hidden cubes.
📢 Institute resource: Provide bilingual (Hindi/English) full‑length mocks as per RDSO Psycho Technical Directorate. Track student T‑Score progress.
📊 Understanding T‑Score in Railway ALP CBAT
T‑Score = Standardized score (mean=50, SD=10). For ALP, qualifying mark = 42 T‑Score in EACH battery.
✔️ If a student scores below 42 in Memory Test even if other batteries are high → disqualified.
💡 Coaching focus: Regular sectional mock analysis to detect batteries that need improvement.
📈 Goal: Aim for minimum 55% raw accuracy in practice to achieve safe T‑Score above 45.
