Aryan, we cannot give reviews on Aakash modules for you but if you have already subscribed to an online course and you have Errorless, you should stick on to it and you should also practise as many sample papers as you can. Attempt atleast one sample paper a week and gauge your performance. Regarding completing the syllabus, assuming that NEET will be conducted in June, you have atleast 6-8 weeks. During this time, you should be able to revise the whole syllabus atleast twice. That will give you an edge. To help you with your NEET preparation, we have NEET Knockout packages that you can check at: https://learn.careers360.com/knockout-neet-may/.
