Many of us cannot understand the things for one view or for one explanation.this is why we get back a step in our studies when compared to others .we need more experienced things to learn easier and to remember the best.this can be done mostly by practicals and also imaginations can be increased by animated things to learn faster and in an easier manner.this is what byju’s is doing to make larners easier understand a hard topic too.and also we can verify our doubts any time anywhere by this app or web page of byju’s .but this is for only paid members.this is a small drawback for the app to develop easily.so I recommend that we can use this app or web page of byju’s to be clear on a topic and to verify our requirements
