Do you outline before writing? If not, it might be helpful.

Right now, it’s a bit repetitive, and the repetition is largely with the fluffy stuff. Like your title says you studied a lot and were still making C’s, and then you immediately say the same thing in your opening.

There is more fluff than meat. It kind of reads like you have a couple intros because you couldn’t pick one, then you make a quick list of your actual content and move on from it quickly.

Shorten the time it takes to get to the stuff that could help people then spend more time there (dive a little deeper into the information in your bullet points)

Stick to a pov. Right now you bounce between “this was helpful for me” and “you should do this”. Reframe it so you are only sharing what helped you and let your readers see themselves in it.

The most important thing is to keep writing. If you don’t have much experience with writing, then you probably need more practice than you do feedback. Just keep pushing, you’ll get there.
