Dear Kratika ,

You can used any kind Video for learning and it is may be helpful but IPMAT  is stands for Integrated Programme in Management Aptitude Test and  it is national level test so we have to prepare accordingly ,because only one source we cant gain learning so we have to choose various sites and more focus on aptitude and some of sites are offering free or paid mock test so appear those test it will helpful and you know the which area you are weak and which area you are strong ,and more focus on weak area ,so prepare accordingly .

I hope it will helpful and best of luck for your exam

thanks
