When I got (get down) to the details of the rules and the exceptions of English grammar, my hands were(are) sweating. The more I read, the more I realized that how many mistakes I have made. I even made lethal mistakes (,even those fatal ones) in my cover letters for job applications. No wonder I get no responses from those hiring companies. On the other hand, (Nevertheless I felt (feel) lost in all the rules and exceptions. It is hard to memorize all the details without using them on a daily basis. Thus, I decide to practice everyday. Try(, trying) to write something and utilize what I have learned. My grammar practice is really weak based (both) on my self-evaluation and feedbacks from others. The good part is that I have a large room to improve (have already realized that there is a large gap for improvement), whereas the bad part is that I have a lot to do to be on the right track (improve).
If I just practice on my own, those blind spots in my wrting may never be found (I would still be oblivious to those weak spots in grammar). So, I need help from you guys. Please help me to correct my mistakes and therefore make my writing better. Hope you do not mind that my writing is really poor (reading my poor writing). I also beg you for the tips towards proper usage of grammar in writing (on writing with proper grammar). Thanks
