Essay explaining a bad semester?

I know the common app has a prompt to explain failure and would this be good at explaining a bad semester I had in High School? It was the spring of sophomore year and It was the only time I made a C in my whole high school / middle school life and with the C I made another C AND on top of that I mad a D. All in that one semester. Due to some personal problems and somewhat just being lazy resulted in this… Now I’m a motivated junior and I feel SOOO bad for this huge mistake. I constantly worry that I won’t get into my dream college (State school with 53% acceptence rate) (btw ive been somewhat of a slacker during middle school and highschool until now)…

My w GPA went from 4.2 to 3.75…
my uw GPA went from around 3.6 to a 3.1… all from that one semester

Studying for my ACTs hoping i’m going to get a 30+ on it.

I’ve changed since then. I’m motivated and driven now I currently have ALL As and plan to take a rigorous course load next year.

So yeah, how Can I improve my chances and explain this on my common app essay? Would this be a good thing to talk about? Also could you guys give me any advice on how to execute my essay for this?

Thanks.

You just don’t…
What are you going to say, that you were too lazy to work lol? It is better if you don’t.

I wouldn’t if I were you. On your essay, only talk about positive things and ignore then negative.

Only talk about negative if it’s like this, “I faced this challenge and overcame it by doing this.”

Your odds say should showcase your progress and accomplishments. If you have a legitimate reason why your semester was bad, mention it to your gc in your ‘bragsheet’ so that they bring it up briefly. If you don’t have a legitimate reason, don’t attract attention to it.
