Dear Niranjan,

If you are clear with the goals and the career you want to pursue or study abroad then you can join the courses on the coursera. Because you can get the quality education compared to the usual schooling.

But, if you are not clear the night would recommend any foundation courses for the IIT JEE / NEET / NDA / KVPY / NTSE or any other olympiad exams. Which can help you gain adequate mental ability knowledge and can even help you in your later phase of study and preparation.

Here is the link for the article of class 9 solution https://school.careers360.com/ncert/ncert-solutions-class-9

Take the decision wisely.

All the best!!

Hello,

Coursera or any other MOOCs courses for that can enhance your knowledge base, for example when you choose to pursue MBA, you have already acquired relevant information, and in a way you're well informed about various aspects, for example if you intend to do major in marketing, you explore various courses pertaining this which will further help you during your post graduate study, now how this will help you during interview, it's just a miniscule part that the members will get to know what all the things you have done, prior to deciding upon your MBA program, and the efforts are worthy, it's just as simple as that, as adding courses aren't just the merely criteria of your selections as you must be aware of the fact that there are number of things taken into consideration for selection such as your overall profile, academic records, experiences if any, and various other important things.

Hi, yes there is no time as well as age limit to pursue what you want. There are many ways in which you can pursue Aeronautical Sciences and/or Astrophysics. But, before anything you will have to decide what you really wish to do Aeronautics or Data Science as these two are very different from each other. Once you have decided what you wish to do you can do on campus or distance learning in that field. You will find it a little difficult to cope up with the studies as its been a long time for you. All the best! Hope this helps.
