can we join cricket club when we are in medical college
Yes as an extracurricular activity other than studies you can play cricket or join a cricket club unless you do not loose your focus from studies. You can definitely play cricket part time as an extra activity to freshen you up from your regular studies.
Of course you can.
College life is about grooming and growing.
You can join clubs of your interest and also take part in whichever competition you like.
Cricket club will not only help you grow but will also help you learning few skills like team spirit, leadership etc.
Good Luck!
