麻烦指点下我的英文日记!
t is only 38 days left. but my mind keep thinking a lot. Since the examination is around the corner,i am compelled to study hard in order to go to the college.because there is no one but longs to go to that place. Those who have the same dream consist the class 86. and when i was in 86. i've learned a lot,not only the knowledge but the friendship.the luckiest thing is that i meet such a wonderful group of classmates and teachers.all the tears and smiles i've left here turn into the most special feeling i've ever had.
perhaps it'll be a long time when i look back on these days.i will miss it.and absolutely i will miss you guys too.
 okay.let us spare no effort to chasing our dreams in the rest of 38 days.
 may everyone in class 86 succeed! and that includes me .
水平有限 请指点我在语法和表达上的问题

Answer 1

But,my mind keeps thinking a lot.
BUT或BECAUSE一般不用在句子开头,如果一定要这么用,建议加上逗号.KEEP要加S因为my mind是单数.
in order to go to "the" college,是你已经有了想去的学校吗?不然in order to go to college即可.
另外,日记一般均为已发生的事情,建议全文使用过去式,除非有特例.
用一些简单的句子与用字为佳,下面以我个人的想法修改了一些,
It was only 38 days left.But,my mind was keepthinking a lot.Since the examination was around the corner,I was compelled tostudy hard in order to go to my dream college.I was longing to go that place!Those who had the same dreams were the class 86.I had learned a lot when I wasin the class.Not only the knowledge that I had learnt,but the friendship Ihad gained.Meeting such wonderful group of classmates and teachers was the luckiestthing.All the tears and smiles I had here turned into the most special feelingever.
Perhaps,it would be a long time before Ilook back at these days.I would miss it,and I would absolutely miss you guys,too.
后面祝语与记录无关,故用现在式.
Okay.Let us spend every effort in chasingour dreams in the remaining 38 days.
May everyone in class 86 succeed!And,ofcourse,that includes me.
