Alevel計(jì)算機(jī)科學(xué)是近年來(lái)非常熱門的一項(xiàng)課程，它不僅能夠銜接本科理工科的相關(guān)專業(yè)，還能夠與商科心理學(xué)社會(huì)學(xué)等人文類專業(yè)相融合，在日后進(jìn)入行業(yè)工作，發(fā)展的道路也是很多的。

同時(shí)，也有很多同學(xué)關(guān)心Alevel計(jì)算機(jī)科學(xué)得A*的難度問(wèn)題，本篇中小編就將結(jié)合課程的考試安排和真題和大家分享一下難度評(píng)價(jià)，一起來(lái)看看吧！

Alevel計(jì)算機(jī)科學(xué)考試構(gòu)成

Paper1?考察計(jì)算機(jī)理論基礎(chǔ)，考試內(nèi)容為學(xué)習(xí)目錄中的前8個(gè)單元的知識(shí)，考試總時(shí)長(zhǎng)為1小時(shí)30分，總分75分。

Paper2?考察計(jì)算機(jī)基本問(wèn)題，考試內(nèi)容為學(xué)習(xí)目錄中9-12單元的知識(shí)，考試總時(shí)長(zhǎng)為2小時(shí)15分，總分75分。

Paper3?考察計(jì)算機(jī)進(jìn)階理論，考試內(nèi)容為學(xué)習(xí)目錄中的13-20單元的知識(shí)，考試總時(shí)長(zhǎng)為1小時(shí)30分，總分75分。

Paper4?考察計(jì)算機(jī)實(shí)際應(yīng)用，重點(diǎn)考察學(xué)習(xí)目錄匯總19、20單元的內(nèi)容，需要大家上交完整的程序代碼和測(cè)試報(bào)告，需要使用到Java，VB.NET或Python作為編程語(yǔ)言。

總體而言，原來(lái)我計(jì)算機(jī)科學(xué)考試的難度是比較大的，他不僅要考察，大家對(duì)于計(jì)算機(jī)科學(xué)理論知識(shí)掌握的是否完全到位，還要考察大家的編程實(shí)踐能力，所以想要獲得A*的好成績(jī)，不僅要在課上認(rèn)真學(xué)習(xí)，還要在課后及時(shí)整理筆記進(jìn)行實(shí)戰(zhàn)訓(xùn)練。
