One of my cousins similarly wanted to secure a seat at IET Lucknow in the 2nd year itself. He mentions that for indeed taking admission in IET Lucknow in the 2nd year, you have to first complete your diploma, and following that, during the 3rd year, you are required to sit for the UPSEE LEET examination.
Depending on the basics of the score you attained in LEET, you can further go on to securing admission at IET Lucknow via lateral entry.
Here is a detailed outlook of the cut off followed by IET Lucknow both in the 2019 and 2020:
Round | 2019 Cut Off | 2020 Cut Off |
1 | 192 | 17624 |
2 | 192 | 23102 |
3 | 233 | 23102 |
4 | 242 | 23102 |
5 | - | 23102 |
Other than that, you should also have a good CGPA, somewhat ranging from 9.0 to above, to obtain a seat otherwise.
