Shu sababli ham Westminsterda o'qiyotganimda INHAda o'qiyotgan o'rtoqlarimga havas qilardim. Chunki web, mobile, va boshqa high-level texnologiyalarni o'zingiz o'rganib olsangiz bo'ladi. Fundamental Computer Science mavzularini esa professorlar bilan o'rganish osonroq va qiziqarliroq (albatta yaxshi professor bo'lsa). Shuning uchun ham universitetni bitirganimdan keyin 2-3ta yaqin dasturchi o'rtoqlar bilan shu fundamental bilimlarni top universitetlarda yozib olingan CS darslaridan o'rganishni davom ettirganmiz. Sizga ham shunday kurslar qiziq bo'lsa, Awesome CS Courses github reposini foydalanishni maslahat beraman.
