Question 1

How accurate is Stratum AI for IELTS scoring?

Accepted Answer

Our neural network is trained on thousands of official IELTS samples. Stratum AI achieves 98% correlation with human examiner scoring across all four criteria.

Question 2

Does it support both Academic and General Training?

Accepted Answer

Yes. Use Academic mode for charts, graphs, and tables (Vision + overview/grouping strategy). Use GT Letter mode for General Training Task 1: tone (formal/semi-formal), every bullet point, salutation & closing, and a dedicated Letter Strategy panel after each check.

Question 3

How does GT Letter checking work?

Accepted Answer

Choose GT Letter in Task 1, paste or generate a letter task with bullet points, set tone and purpose, then submit. The AI scores Task Achievement on bullet coverage and register — not chart language — and returns letter_strategy with per-bullet feedback and a full model letter rewrite.

Question 4

Will using Stratum AI help me reach Band 8.0?

Accepted Answer

Absolutely. By identifying your recurring grammar strata and providing high-level lexical upgrades, Stratum focuses on the specific gaps preventing you from hitting Band 7.5+.

Question 5

Is my data secure and private?

Accepted Answer
