Definitely!

The Leader batch of ALLEN is a one-year course specifically designed for the students who have passed the 12th class examinations, or who are giving JEE for the second time.

All the concepts are cleared in the class and the teachers are very good. Since it is a repeater batch, the course is covered at a faster pace and it becomes difficult at times to match the pace, but if done correctly, clearing JEE with a great rank is almost guaranteed.

The test series of ALLEN is also too good and it helps you to practice in a limited-time environment with a huge of number of students giving the same exam. Since ALLEN's tests are given by a huge number of students, thus, the rank prediction is also quite accurate. Overall I would say that the program is very good for those who have a firm determination to crack JEE.
