Total	100	200	60 Minutes

Each question carries 2 marks.
There is no sectional time limit mentioned for Tier 1 in some sources, but other sources mention a 15-minute sectional timing is expected to be applied.

Tier II: Computer-Based Examination

Tier II comprises three sections, each with two modules, and also includes a Skill Test/Typing Test.

Session	Section	Modules	Number of Questions	Maximum Marks	Time Duration (Each Section)
Session-I	Section-I	Module-I: Mathematical Abilities	30	90	1 hour (for each section)
