best age for students to get graduate
There are no best age to get graduate. If you want to study then you can do graduation at any age. You have to keep in mind to join a graduate course you need to be at least 17 years of age to be eligible for admission. Apart from this its always optimal to get graduated with in 25-30 years age depending on the course you are studying. The reason behind this is because, from the employability aspects, most companies want employees to be at a tender age so that they can give the maximum output. But that doesn't mean at a greater age, it doesn't matter. So your question is quite sensitive and it can be explained in different aspects and above I have mentioned some of them.
I hope this answer helps. All the very best for your future endeavors!
