Дээрх 3 шалгалт нь Онолын шалгалтууд бөгөөд лабороторийн шалгалт нь тусдаа 30 онооны шалгалт байдаг. Та нийт авах ёстой онооныхоо 30%-иас дээш авж байж шалгалтандаа тэнцэнэ. Нийт 5 шалгалт өгсөн л дө үлдсэн 2 нь хоёулаа хэлнийх байгаа дүрмйинх, гүнзгий түвшнийх гэсэн. Тэр хоёр бол нээх чухал биш дээрх гурван шалгалтны нэг нь бол бүүр ч чухал биш “Компьютерийн үндэс” учир нь энэ хичээл дараа нь дипломон дээр тавигддаггүй. Та зүгээр л тэнцэх хэмжээнд л өөрийгөө бэлдээ л ороход болно. Хамгийн гол нь мэргэжлийн хичээлүүдээ л сайн өгөх хэрэгтэй. Заза тэгээд таньд л гэж хэлэхэд Энэтхэгт сурахад ёстой амархан та онц сурлагатан болж шалгалтын дараа самбар дээр гарна гэж зүтгэвэл хэхэ таниас нилээн хөдөлмөр шаардах байх л да харин зүгээр сурах юм аа сураад шалгалтандаа уначихгүй яваад байя гэж бодож байвал та зүгээр л өдөр нь үзсэн хичээлээ орой нь сөхөж харчихдаг л байхад болно. За амжилт хүсье наашаа ирж сурах гэж байгаа оюутан залуусдаа Зүгээр л хүрээд ир энд бол бүх юм амархан хэхэ. (ГЭХДЭЭ САЙН СУДЛААРАЙ.)
