The above comments are nonsense...I would tell you one thing .... consider the 9th grade as a fresh starting point if you were not good in classes before this... 9th grade is your chance to start fresh.. many people change during freshman high school but one thing you have to remember is your hard work now is going to pay of when you take your 12th grade exams .... a lot of people that considered them selves cool and what not during high school are all going to be screwed and most join private universities with nonsense fields ... so I would suggest taking the 9th grade class seriously... and I don't think you should study it now just learn it well during the year and take 10 the grade summer class next summer so it will be easier for you to revise both 9th and 10th grade for next year's matric... Good Luck!👍🏽
