This is Acad Note Dealer. I deal with notes I made as I make my way up the education ladder. Thus far, what's available is Biology, Chemistry and Economics. I will be doing accounting in the future and accounting notes/materials will then subsequently be posted. If you have any queries, or if you wish to make a contribution (such as a weird prelim/promo question, or any thing else useful), then you can contact me at yujiro3141592@gmail.com Thanks and all the best in your studies, whoever you may be!
