As you said siddiss, you don't learn chemistry and this might be a problem when it comes to the organic part....if you don't understand the reactions, u might hv to learn them!! However, there is another way....try making mindmaps or sumthing visual that connects the reactions....it is especially useful if u hv a photographic memory....all u hv to do is stare at it
and hopefully ull brain will be able to recall the reactions by trying to visualize the drawing (or whatever u make)...
Here are some examples attached =) sorry if they aren't so clear
my scanner isn't working so i had to take a pic of it frm a book
enjoyyy
and goooooodluck in all ur exams!!!
