Ngokusekelwe emagameni ezigatshana, umfundi angathola nomqondo wokuthi yini okumele agxile kuyo esigatshaneni ngasinye. Izindinganiso eziningi zomkhiqizo wokugcina zingafundwa kuthebula lokuqukethwe ukuze uthole umbono ojwayelekile. Kubasebenzisi abangenalwazi bezinga, sincoma ukuthi uma ubona amagama ezigatshana, ucabangisise ngezimo eziyingozi ezingase zihileleke kuleso sihloko; kubafundi abanolwazi, ithebula lokuqukethwe empeleni liyiwindi elisheshayo elingena ezingeni. Amazinga amaningi e-IEC anokwakheka kombhalo okufanayo, ikakhulukazi ezigatshaneni eziyisithupha kusukela kwesokuqala kuya kwesesithupha, zonke zikhuluma ngesihloko esifanayo. Izigaba ezilandelayo, ngenxa yemikhiqizo ehlukene, izidingo ezihambisanayo zihlukile, ngakho-ke zigxila ezihlokweni ezahlukene. Ngokombono wezokuphepha, zonke izigatshana ezisohlwini lwaleli zinga zingahlukaniswa ngokulinganayo ukuze kuvinjelwe lezi zinhlobo ezinhlanu zezingozi ezilandelayo, okungukuthi, ukushaqeka kukagesi, ukulimala okushisayo, ukulimala komshini, izingozi zomlilo, kanye nezingozi zemisebe noma zamakhemikhali. Izinga lihlukanisa izigaba ngokuya nezici zesakhiwo nemisebenzi yomkhiqizo. Izithasiselo-Isithasiselo singathathwa njengezigatshana zomushwana eziyinhloko, ezingaba nemininingwane eyengeziwe nezimfuneko eziqondile zezigaba zomshwana eziyinhloko (njengeSithasiselo B kanye Nesithasiselo S), noma izincazelo nezincazelo ezinemininingwane yezigatshana eziyinhloko (njengeSithasiselo K. kanye neSithasiselo M) noma imihlahlandlela yokusebenza eqondisayo (njengeSithasiselo O kanye nesiThasiselo Q). Okuqukethwe kwabo akukona okunqumayo ukuze kuqondwe izinga.
