Hi Pramod,

               I hope you are doing good. Now Coming to your query. You didn't mention for which entrance test you want to take long term. Nevertheless, Dera taking the long term or not completely is completely your choice there is nothing right or wrong in it. For example you didn't get a good rank in some particular entrance test due to that you are not able to get good colleges then you here you have three ways. One is if you are not particular about any college which means if you have belief in yourself and can work very hard so you are OK with any college then join whatever college you will get for your rank. The second way is you are very passionate about study in some particular college and you don't want to compromise on it then if possible join in that college through management quota if you are affordable. The third way is that you are very passionate to study in some particular top college  but you didn't get good rank at the same time you can't join that college through management quota due to financial status or that college doesn't provide money paid seats and you don't want to compromise then to follow your passion you choose the long term.

Do What you feel right.

I hope this helps.

All the best.

Thank you.
