How to remember all the reactions and the reagents and catalysts simultaneously?

@ vamshi 
practice is the only thing that can save you in organic chemistry , 
frst of all when u are reading from ncert , underline all reagents and reactions as well as the catalyst involved . 
after that write down the condition in which these catalyst can be applied to a perticular reaction . 
then take a sheet of paper , enlist all the reaction and reagents their . 
and paste it in your study room , and each day morning just have a look at the reactions only . 
and u can write it in ever weekends to enhance your memory .,
and if u are clear with mechanism , i dnt think u will face any kind of difficulty in remembering them . 
ALL THE BEST ..
