Which class should I choose?

Hey guys! I am an international student currently studying in Canada, Toronto. Its my final semester and I am hesitant to choose which teacher I should pick. (The course is Grade 12 English) If I go with K, I will suffer 2 months and I am done but if I go with S, I will suffer for 3 months with teacher that I know.

Teacher K (3/9~5/4)(Faster finish date because of 2 class per day 3hr)

• First time taking his class(Took 3 times already)
• Constantly throws in horrible jokes during lecture time( not funny at all)
• Other students say he give grades based on student’s performance(some say he gives higher marks to girls)
• Took his class for 3 days and god damn he is boring
• The course content is 2 novels and 2 units about media/ writing

Teacher S (3/9~6/25 normal 4 month semester with him, I took Econ,Business and English with him before, 1 class per day 1hr30min)

• He is enthusiastic about his courses and he also wrote my reference letter
• He knows my potential so he gave me good predicted grades
• But, this doesn’t mean that he will give me good marks in this course (Shakespeare)
• The course content is 2 units with media and writing and 2 Shakespeare plays.

Who should I pick guys??? Deadline for change is tmrw and I am still confused. My target mark is minimum 80% in this course but I want to reach 90% for higher average percentage.

Any advice will be highly appreciated!
