How to improve clarity?

[The Cat In The Hat]

So I got this feedback on my English trial exam: 'Work on clarity because your essays are excellent'. I was wondering if anyone could shed some light on how to thus 'work on clarity'. What can I do to improve it? Will improving that pick my scores up from the 17-18/20 band to maybe 18-20/20? What else can I do for that?
Thanks!

I know this probably isn’t much help but my teacher said to me my ideas were great also but clarity. It could be:

1. Innapropriatley long senteces which run away from you. Maybe try colons?

2. You aren’t writing down the whole idea- this isn’t to say use thousands of words but maybe you aren’t explaining what you mean in full due to being under time constraints so the meaning is lost. With this maybe just sub-vocally proofread and see whether certain words or even the whole concept you were trying to write about has gotten through.

3. This one was mine but maybe the author and the characters were getting mixed up. I doubt you made this mistake but I’ll just put it here in case someone reads it: always use the authors last name or “playrights” (if your doing a play obviously). If you say “they did this to xyz” or use it her pronoun after giving evidence involving characters it could get confusing.

I know what I said above most likely doesn’t apply to you because your getting 8-9/10 already but I hope it helped a little- your always so helpful on my posts
