解析：
【小题1】去掉in 在英语中，last year, this year, next year前面不能加介词in.故原句中应删除in.
【小题2】excited 此句意为：……我非常激动。此举中的动词felt为feel的过去式，为系动词用法，应用feel + adj.的结构。exciting意为“令人兴奋的”；应该为：excited(感到兴奋的)。
【小题3】usefully—useful 此举中的get在这里为系动词用法，即用get + adj.的结构。故usefully应该为形容词形式：useful.
【小题4】that—what 在宾语从句中的引导词that本身无词义，只是起到引导作用。而what在宾语从句中既做引导词同时是宾语从句的主语。故that改为what.
【小题5】have-had 因为前文为In the past,故动词应该用一般过去时。所以have要改为had.
【小题6】but—however 英语中的but连接句子时不能用逗号(,)隔开。故此处的but应该为however.
【小题7】did—do 根据前句When an exam is ing,可知应该用现在时，所以句中的did应该为do.
【小题8】tell me the right 此句意为：……告诉我正确答案。在此应为特指，故在right前加上the.
【小题9】very—more 因为句中有…than before.句中应该用比较级，故very改为more.
【小题10】prepare后加for 英语中的prepare sth.意为“准备什么事情”，宾语是所准备的内容。而prepare for sth.意为“为……做准备”。for表示准备的目的。此处应为：为考试做准备。在prepare后加for.
