Mayelana nalolu hlelo lokusebenza

Imibuzo eyi-12 edlule evela ku-2nd Class Telecommunications Construction Management Examination kusukela engxenyeni yokuqala ye-Reiwa 7 kuya ku-R1 (ingxenye yokuqala ka-2025/ingxenye yesibili ka-2024/ingxenye yokuqala ka-2024/ingxenye yokuqala ka-2023/ingxenye yokuqala ka-2023/ingxenye yesibili/ingxenye yesibili/ingxenye yokuqala ka-2020 2021/ingxenye yokuqala ka-2021/ingxenye yesibili ka-2020/ingxenye yesibili ka-2019/ingxenye yokuqala ka-2019)
Kulabo abahlose ukudlula ngokudlula emibuzweni edlule.
Azikho izindleko zangaphakathi nohlelo futhi azikho izikhangiso.
Ungafunda ngokuphindaphindiwe ocingweni noma kuthebhulethi yakho.
Funda kancane kancane ngesikhathi sohambo lwakho lokuya emsebenzini esitimeleni noma ebhasini noma ngesikhathi sakho sekhefu.
*Kuhlanganisa ingxenye yokuqala yeReiwa 6 (ingxenye yokuqala nengxenye yesibili), ingxenye yokuqala yeReiwa 5 (ingxenye yokuqala nengxenye yesibili), ingxenye yokuqala yeReiwa 4 (ingxenye yokuqala nengxenye yesibili), ingxenye yokuqala kaReiwa 3 (ingxenye yokuqala nengxenye yesibili), Reiwa 2 (ingxenye yesibili), kanye noReiwa 1 (ingxenye yokuqala nengxenye yesibili).
*Cha. 51 engxenyeni yokuqala ka-2024 ayifakiwe ngenxa yezizathu zokubonisa.
Embuzweni ngamunye, impendulo ingabhekwa ngokushesha ngokuchofoza [Umbuzo ⇒ Phendula].
Umbhalo wombuzo nawo ubhalwe ekhasini lempendulo, okwenza kube lula ukubuyekeza imibuzo.
Ifanele ukubukeza imibuzo edlule.
I-"Learning Confirmation Test" (u-R6 ukuya ku-R1) ibuza imibuzo eyi-10 ngokungahleliwe, ikuvumela ukuthi uhlole ukuthi uziqonda kanjani.
Enye yezinto ezibalulekile okufanele uzenze ukuze uthole iziqu ukubukeza imibuzo edlule.
Ngokubukeza imibuzo edlule, ungaqonda ukuthi hlobo luni lwesakhiwo semibuzo esisetshenziswayo, hlobo luni lwemibuzo evame ukuvela, kanye nezindawo zakho zamandla nobuthaka.Ungaphinda usebenzise imibuzo edlule ukuze uhlele ukulungiselela ukuhlolwa kwakho nokulungiselelwa ukuhlolwa, njengokuthi yiziphi izindawo ongagxila kuzo nokuthi yiziphi izindawo ongazuza kuzo amaphuzu.
Zitholele eyakho indlela yokufunda nokufunda ngendlela ehleliwe.
