use schweser (99% of the time) but do refer to the CFAI readings for IPS and PM for Institutional Investors, ethics plus Behavioural finance
some topics on FI ( like cupsy bonds, synthetically adding and removing call option on the bonds) was not even covered by schweser
duration of swaps was not explained by schweser last time around ( CFAI had detailed explaination)
these are few of the things which were important and were missing from schweser
hope this helps , well if it doesn’t like hell I care
