短文改错

Recently,I have made an investigation on（on 去掉） that examinations in Grade 3 should be difficult or easy.Oppinions differ.Some students prefer difficult exams.In their opinions,such exams will cause them （增词 to） think hard (变成 harder) and meet the challenges more bravely.Meanwhile ,they can find out the existed (变成 existing ) weaknesses and then improve their study methods furtherly (变成 further ).However,other students are in favour of easy ones.They think too difficult exams will (增词 not) encourage them and even they will be afraid to attend in (变成 to ) the coming collenge(这里的college 是不是打错拉~~) entrance examinations.But in easy exams,they are more like (变成 likely ) to get high marks and naturally more confidence will be gained.As far as I'm concerned ,difficult exams are much to my taste.For one thing ,it is sure that we can accumulate more experience on how to solve difficult problems ;for another,we can get ourselves well prepare (变成prepared ) for the exams.不知道题目的要求是什么？？？所以大致找了一下~·不知道lz是否满意~~期待您的好评，希望对您有所帮助！
