SBL paper advise

this is my first professional level paper and i am really struggling with descriptive type question since not used to it in skill level paper . I am thinking about attempting SBL for June attempt

I can allocate 32 days till exam for studying full time. I can study for atleast 10 hours day and have previous done so as well . This would give me around 32*10= 320 hour of studying and Out of those (320) around (40) hours would be spent on mock in exam condition so that leaves me with (280) hours would this be enough to clear SBL?
