If a student writes both papers, the best of 2 will be considered for final scoringWe encourage students to attempt our mock test to get a handful of experience with the type of questions and using the online platform.The exam can be attended from any Desktop/Laptop/Smartphone/Tablet.You must use Google Chrome Browser

Other browsers such as Mozilla Firefox, Safari, Edge, etc. are not supported.

**Exam Instructions:**

- Time Allotted: 2 Hrs 30 Min
- Make sure the Email ID and Hall Ticket Number entered are the same as given during the registration.
- This question paper consists of 5 sections, of which at least 4 must be attempted.

Section 1 (Mathematics): Students opting for Engineering

Section 2 (Biology): Students opting for Medicine

Section 3, 4 & 5 (Physics, Chemistry & LR): Compulsory for all the students

* If a student attempts all the 5 sections, he/she will be considered for both Engineering and Medicine streams. During the time of personal interviews, he/she will be able to choose which stream he/she wants to pursue. - Every Section has 20 Single Correct Multiple Choice Questions.
- MARKING SCHEME:

Correct Attempt: +1 Mark

Un-Attempted : 0 Mark

Wrong Attempt: -0.25 Mark

*Every wrong attempt reduces 0.25 mark, we suggest students avoid any guesswork - You Must submit the responses before the timer ends. You will be unable to submit if the time of the exam is over.
