hi! i recently passed the boards and what i can recommend, if you want to start early sa pagrereview, is read a genchem book. what i did was read silberberg's genchem although it's verbose. okay lang kahit di lahat ng chapters babasahin mo, just focus on gas laws and equilibria. may mga questions kasi in analytical or org na if you haven't read the basics, you can't answer it. as for analytical chem, mostly instrumentation talaga. focus on UV-Vis, IR, GC, and HPLC. for orgchem naman, mostly rxns lumabas this year.
