📢 1. Blog Analysis

Academy Preference Strategy: While filling the form, your **Order of Preference** (e.g., AFA > IMA > OTA) matters significantly. If you are eligible for Flying Branch (AFA), always keep it as 1st preference. For non-math students, OTA is the primary entry route. Remember, OTA candidates do not need to attempt the Math paper.

📖 2. Exam Pattern & Syllabus

Written Exam (Offline Mode):

  • Paper 1: English (100 Marks): 120 Qs (Grammar, Comprehension, Vocab).
  • Paper 2: General Knowledge (100 Marks): 120 Qs (Polity, History, Geog, Science, Current Affairs).
  • Paper 3: Elementary Math (100 Marks): 100 Qs (Arithmetic, Algebra, Trig, Geometry, Stats). *Not for OTA candidates.

🎯 3. Strategy for April Exam

1. English is Key: This is the easiest scoring section. Target 70+ marks here to clear the overall cutoff.
2. GK Cutoff: Many engineering students fail the sectional cutoff (20%) in GK. Focus on Science and Current Affairs (last 6 months) to stay safe.
3. SSB Interview: The written exam is just the gate pass. The real test is the 5-day SSB interview. Start working on your physical fitness and spoken English now.
