You surely made a lot of spelling mistakes. Make sure you recheck your work before submitting it.
The students' places of origin are four countries: Indonesia, Hong Kong, Malaysia and Singapore.
It sounds quite weird. I think this sounds better "The students originates from four countries which are Indonesia, Hong Kong, Malaysia and Singapore."
We can see that overall trend of coutries had in two decades a stedy increse
Avoid using personal pronoun such as "We". Your sentence is also grammatically incorrect and makes no sense. I prefer "The overall trend increased steadily over the two decades"
It is interesting to see that the number of overseas students in Malaysia was around 10.000 of people in the first decade.
Is it not "Malaysian students in Australia"?
The trend of Indonesian student gradually incresed from 1987 to 1996 when reached a high point of 19.000 of people in 1997.
"The trend of Indonesian students gradually increased between the year 1987 and 1996 and reached its peak of 19000 people in 1997"
Number of students who come from Singapore remained constant for the first eight years. Afterwards, the number of students quickly rose in 1990 but in the overall the amount of people was the lowest regard all countries.
"The number of students who were from Singapore remained constant for the first eight years but rose dramatically in 1990. In spite of that, the number of Singaporean students were the least among all."
It obviously sounds better.
Well, there is no chart so I may make some word mistakes in my correction.
Overall, I think you should practice more.
Hope this helps :)
