# LTSE 2022 ## Test Dates

Lead trust has finalized the exam dates for LTSE 2022. You can write one or both of the tests. Best score from the two will be used for your ranking. Students can also attempt the Mock test before the final exams.

Exam dates:

• Mock Test: 2PM IST, 2nd January 2022 (Sunday)
• Test1: 2PM IST, 9th January 2022 (Sunday)
• Test2: 2PM IST, 15th January 2022 (Saturday)

## Mode of exam

### Online :

• It is not compulsory to write both the tests.
If a student attempts both the papers then the best of 2 will be considered as the final score.
• We highly encourage students to write our mock exam for getting a handful of experience on the type of questions and using the online platform.
• Login details: Registered email ID and Hall ticket number.
• The exam can be attended from any Desktop/Laptop/Smartphone/Tablet.
• You must use Google chrome browser.
Other browsers like Mozilla Firefox, Safari, Edge, etc are not supported.
