writing refresher for ENEB

[jb111]

Hi all - haven't written a paper in 2 years and rusty.  I grabbed the ENEB deal but lost a year due to COVID-induced depression (lost 2 family members to cancer of all things).  My head's in a better place now and starting to look at the ENEB materials.  Other than Googling, do you suggest any other resources to touch up my writing skills?  I don't want to take too long-being so far behind on ENEB  
Other than what the syllabus says, any tips on what ENEB is looking for?  I'm starting with Strategic Management.  Thank you
