Is it better to learn three and four courses at one time or to learn one by one

Question

in sololearn I had seen many times that many people learn many courses at one time but I think that it is not good.we have to learn one by one. what do you think. tell to me

Answer 1

learn one by one
/*u can complete a course in 1 day & can write codes easily but for understanding it completely it takes months (here is very very few knowledge )*/

Answer 2

@BlazingMagpie you are right. But there are some courses that can't be finished in one hour.

Answer 3

Just focus on one at a time, you can finish it in an hour or so.

Answer 4

I suggest you to learn one by one as this helps in learning the others also.
