Read all the reagent by correlating and making group among the different reagents. As oxidation based reagents, reduction based reagents, cis addition reagents,anti addition reagen...
The trick to make reagent easy is to group them by functional groups.
For eg Oso4 and KMnO4 in one group as only for hydroxylation
Nabh4 and lah etc.
