Howz toz revisez Computerz Science
Practicez questionsz fromz pastz papersz arez onez ofz thez bestz methodsz ofz revisingz topicsz fromz thez
course.z Thisz approach,z accompaniedz byz creatingz notesz andz readingz thez coursez textbookz asz az
sourcez forz information,z hasz provenz successfulz forz manyz ofz ourz previousz students.
Howz toz revisez az particularz topic
thisz isz genericz andz byz noz meansz az onez sizez fitsz allz approach
1. Onz az singlez sheetz ofz A4,z writez downz everythingz youz currentlyz knowz aboutz thez topic.z
Doz thisz priorz toz readingz thez coursez textbookz orz seekingz helpz fromz previousz notes.
2. Nowz consultz coursez textbookz forz thez topicz andz addz toz thisz sheet,z anythingz youz didz
notz knowz thatz isz necessaryz –z oncez complete,z highlightz thesez pointsz –z thesez arez thez
areasz youz needz toz learn.
3. Locatez questionsz basedz aroundz thisz topicz inz thez pastz paperz packz andz attemptz toz
answerz them.
4. Confirmz withz thez markz schemez asz toz yourz successz inz answeringz thez question.
Thez endz goalz ofz thisz approachz wouldz bez thatz youz arez comfortablyz ablez toz producez az piecez
ofz A4z forz eachz topicz ofz thez coursez andz thenz applyz thisz informationz toz thez pastz paperz
questions.
Obtainingz feedbackz forz answers
Thez studentsz whoz succeedz thez bestz inz computerz sciencez arez thosez whoz seekz constantz
feedbackz fromz teachers,z notz justz inz thez scopez ofz az lesson.z Anyz workz youz producez outz ofz
lessonz suchz asz pastz paperz questionz answersz orz programmingz challenges,z youz shouldz wantz toz
seekz feedbackz for.z Thisz canz bez achievedz by:
1. Takingz workz toz az teacherz duringz schoolz time.
2. Emailingz az teacherz yourz answers,z questionsz etc.
