Dont join Allen. You will face extreme partiality. Eight batches per phase, two top batches for boys and girls resp. What about the other batches? Masti.
Don’t get misled by advertisements of allen like 8 ranks in top 10 in aiims etc. They are the students of special rankers batch. They have separate extra classes, special library facilities which an ordinary student doesn’t get.
Most people praising allen are those that love the masti part(most not all) and of course the toppers who got special treatment. I know my answer will be downvoted by them but if I can save at least one person’s career through this answer, I will feel blessed.
