Hey priyashi,

See, these decisions are totally upto you. As i have been a regular student so i'll share my experience with you.Basically if we see then there are many advantages of regular schooling. These are as follows:-

1) you get the chance to clear your doubts in any topic with your teacher.

2) you get the chance to learn your subjects theoretically as well as practically.

3) you are awared about all the equipments used in physics, chemistry or biology labs which might help you in further studies.

4) being a regular student would also help you to develop your personality enhance your communication skills as well.

5) also besides studies there are a lot Activities in which you take part in and you learn a lot of skills like team work, leadership etc.

Whereas talking about non-attending you might not get these advantages but yes there are some which you might get and those are:-

1)You would be able to join those 5-6 hrs of coaching such as FIITJEE, Akash etc.

2) You would get enough time for preparation for your competitive exams.

Hope it helps.

Good luck.
