Yes the maintenance allowance will be given on time there can be a delay of 4-5 weeks but it doesn't matter we just have to keep patience and not to panic, this year also the allowances came a little late like if the student has started his 7th sem and he is receiving the maintenance allowance for 6th sem .So utilize your allowances properly, save the money so that it can used if there is any other delay.
I believe there is no point for calling AICTE helpline again and again just to ask them for allowance because they will release according to their time only. Call AICTE only if there is some problem in your portal.
