Well, As far as academy notes are concerned, yes they are helpful to some extent in order to get them touched and their way of notes making, presenting the main points, synopsis, and after having studied those notes, one can make his/her own notes comprehensively. However, It is general perception that the academies notes are not well enough. But, I think they are beneficent. However, I don't use others notes because one has his/her on way of studies. If you have limited time or doing job somewhere than it would certainly be beneficial for you to go for notes. And, if you have pretty good enough time. Yes, Then you can go with your own way, may be notes making. To the conclude, yes notes are beneficial in the said condition, but it depends on the individual......
