i hv cleared all my CA exam (CPT to Final) by night study only cause i was not able to get up early in morning. Same thing in office i used to go late in morening ( ha sir sometime sought) but leave late from office so its matter of concentration and work completion on time otherwise koi bhi time ho does not make difference if u r comfort...
a student can study any time during a day as per his or her convenience...but to compromise with his or her sleep,i think its not a good thinking... anyways Priyanka mam,thanks for sharing .....
