"Kurz je prehľadne vysvetlený a názorne na videách ukázaný. Podľa návodu sa pracuje super, jednoducho a celkovo je to super spracované. Podľa návodu všetko pracovalo správne. Všetky návody sú primerane dlhé, vôbec nespôsobujú ani nenavádzajú na "nudu". Odkazy na pomocné stránky uľahčujú prácu a sú na nich aj príklady s vysvetlením. Kurz sa mi celkovo páči. Ďakujem, za Váš čas ktorý ste strávili pri natáčaní kurzových videí."

"Rada by som odporučila tento kurz tomu kto by sa v budúcnosti chcel venovať tvorbe web stránok. Ja som bola veľmi spokojná. Videá a prednášky boli zrozumiteľne vysvetlené a prehľadné. Celé to bolo kvalitne urobené. Ak som mala nejaký problém, tak pán Dufek mi cez Skype hovor všetko vysvetlil a objasnil. Vrelo odporúčam tento kurz."

"Pokiaľ ide o mňa, tento kurz sa mi veľmi páči. Tým že je to vizuálne, že všetko čo robíte patrične komentujete, mám o tom lepšiu predstavu. Takže za mňa plus. Samozrejme vždy je na čom pracovať, no mne sa to páči aj takto. Tento kurz som už doporučil aj svojmu kamarátovi. Klobúk dole."
