Allen batch

I need some advice regarding joining Allen batch for class 12. I'm confused between the 20th Jan batch (Phase 2) and the 18th Feb batch (Phase 3). My 11th syllabus isn't completed yet, but by my calculations it will get over by 13th Feb. However, my father is suggesting I join the 20th Jan batch because the academic counsellor from allen said that I should not waste my time here and join the batch from 20th Jan, there they take revision classes and doubt classes where I can complete my syllabus par yaar revision lecture se first time kaise padh paunga koi chapter me as I still have over 140 lectures (each 1-1.5 hours) to complete for my 11th syllabus. Me confuse hogaya hu ki if joining the earlier batch would be wise or if I should wait until my syllabus is done. Pic of my remaining syllabus (the numbers represent no. of lectures and tally mark represent lectures completed aur sirf chemistry aur physics ka syllabus dala hai kyuki I am dependent on coaching for maths syllabus completion, teacher said he will complete by February mid )
