Dear aspirant !!

Hope you are doing great ! Tell me , if you any other option except one shot ? Your answer will be no , if you are attempting June session then only one shot are beneficial , watching 4to 5 hours lecture will be not worth at this time .

Firstly watch one shot , do previous year question and then do mock test . This should be your strategy at this time.  Rest depend on you !
