English is taught in Swedish schools as a foreign language. The students are at different levels, and most of them try to achieve a higher proficiency level. While the extent to which students are successful at learning a language depends on many different factors. Previous studies have shown that students who are open to taking risks in their production are at an advantage.

The present study investigated 80 texts written by students in the seventh and the ninth grade. The main aim was to investigate to what extent errors and complexity levels can be explained in relation to risk taking. In more detail, the study examined differences between the grades in terms of degree of syntactic complexity and what kinds of aspect and tense errors were made. To be able to investigate the errors an approach called Error Analysis was used.

The results showed that for both grades, substitution errors were the most common error and there was a significant difference between the grades (p<0.001); however, the other errors showed no significant differences. Regarding the complexity levels, there was a highly significant difference (significance level p<0.001) for the least complex sentences, but there were no significant differences between the grades for the highest and second highest levels of complexity.

The results furthermore suggest that there is a correlation between risk taking and a higher likelihood of making errors, as a large proportion of the erroneous sentences written by students from the ninth grade were found in syntactically complex sentences. Most of the errors made by students in the seventh grade were found in less syntactically complex sentences however.
