　　根据官方数据显示，2016年超过370000名学生在888所学校参加了超过730000次AP考试。Trevor Packer(head of AP,College Board)于2016年六月份在Tweet上公布了2016年全球AP各科成绩分布表，并对各科成绩的变化做出评论。
　　AP Score Distributions
　　1 热门考试科目成绩分布及官方评论
　　Trevor's Comments：While the exam was challenging for many, AP Physics 1 scores improved over last year: an increase of 2.3% in scores of 3+ in North America.
　　The AP Physics data don't yet include international students, which typically boost AP Physics scores of 3+ by another % point or two.
　　Multiple-choice questions on Science Practice 5 (Data Analysis & Evaluation) posed the greatest challenge to students.
　　FRQ1 (rotation/forces) & Q5 (waves) half of students earned no more than 1 of 7 pts: spr.ly/6019Btp5B
　　1 student, out of ~150,000 scored so far, earned a perfect score of 80/80 pts on this year’s exam. No student had yet done so.
　　Trevor's Comments:Usually, we don’t see so much score improveme trend continues w/Physics C:E&M: a significant boost in %5s over 2015.
　　Scores were highest on this FRQ2 (circuits): spr.ly/6016Btb8j
　　Students struggled with FRQ3 (magnetostatics), with 60% earning 3 or fewer pts (out of 15) on it.
　　1 student, out of 27,000, earned all 90/90 points possible on this year’s AP Physics C: Electricity & Magnetism exam.
　　Trevor's Comments：These don’t yet include the scores from outside North America.
　　Congrats to AP Calculus BC teachers & students: the strongest performance in years, so a significant growth in the % of students earning 5s.
　　Lowest mean score on AP Calc BC: Q6 (Taylor series); many also found Q2 (parametric particle motion) tough: spr.ly/6014Bt6zu
　　2 students, out of 125,000, earned perfect scores of 108/108 points possible on this year’s AP Calculus BC Exam.
　　Trevor's Comments：These don't yet include the scores from outside North America.
　　The AP Calculus AB data are in: students demonstrated stronger skills this year than last, achieving a higher % of 3s, 4s, & especially 5s.
　　Among the AP Calc AB free-response questions, the highest mean score was on Q4 (slope field):spr.ly/6017BshFx
　　Many students struggled with Q2, 3, & esp 5 (modeling volume / related rates), w/31% earning 0 pts on it: spr.ly/6014Bsh2i
　　11 students, out of 310,000, earned perfect scores of 108/108 points on this year’s exam.
　　Trevor's Comments：Students have shown slightly stronger mastery of AP Chemistry this year than last year’s group did, increasing the % of 5s in particular.
　　Students generally scored best on Big Ideas 1&2, lowest on Big Idea 3 (transformation).
　　In the Free-Response section, AP Chemistry students performed best on Q5 (kinetics / gas laws: butadiene).
　　FRQ6 on equilibrium/stoichiometry (EDTA) stumped the
73% earned 0 points on it: spr.ly/6016Btung
　　Trevor's Comments：Scores are generally lower this year than last, but still higher than 5 yrs ago when 50% fewer participated.
　　Students did quite well across multiple- the most challenging were on firm behavior and market structure.
　　Scores were generally highest on FRQ2 (consumer choice) & lowest on FRQ3 (monopolistic competition): spr.ly/6018BstTM
　　47 students worldwide (out of 83,000) earned all 90 points possible on this year’s exam.
　　Trevor's Comments：Once again, AP Computer Sci = the fastest growing of all AP great to see more schools providing this critical opportunity.
　　Students did quite well across all topics in the multiple-choice questions, esp. logic/software eng/recursion.
　　In order to get a 3+, students need to earn pts on the FRQs; students getting 1s/2s can’t do much w/these: secure-media.collegeboard.org/digitalService…
　　5 students, out of ~50,000, earned perfect scores of 80/80 points possible, on this year’s AP Computer Science A Exam.
　　Trevor's Comments：Nice work: students taking AP Statistics this year demonstrated stronger mastery overall, so there’s a solid increase in the % earning 3+.
　　The questions on probability/simulation were the most challenging for many students. Most students got &5 of 10 right.
　　Similarly, the AP Statistics FRQ4 (probability/simulation) was most difficult, w/ ~half of students earning 0/4 pts: spr.ly/6019BQEx5
　　The AP Statistics free-response questions’ mean/max scores: Q1: 43%, Q2: 31%; Q3: 39%; Q4: 25%; Q5: 32%; Q6: 40%.
　　1 student, out of ~200,000, has earned a perfect score of 100/100 points possible on this year’s AP Statistics exam.
　　Trevor's Comments：Interesting pattern in AP Physics C: Mechanics this year: a shift in student performance to many more 5s, a few more 2s, & fewer 3s, 4s, 1s.
　　Students generally did very well on FRQ1 (Newton’ kinematics), & than a fourth of them earning most of the pts.
　　Many AP Physics C Mech students struggled w/FRQ3 ( Newton’s laws), a third of them earning no more than 1 point.
　　1 student, out of 53,000, earned a perfect score of 90/90 pts on this year’s AP Physics C: Mechanics exam.
　　Trevor's Comments：Good predictor of whether you scored high on this year’s AP Bio exam is how well you did on Q4 (gene expression):spr.ly/6011BQea5
　　AP Biology multiple-choice: students scored very well on Big Idea 2 (cellular processes), and least well on Science Prac 2 (using math).
　　AP Biology grid-ins that require mathematical calculation: students performed quite poorly: more than 50% earned 0 or 1 pt out of 5.
　　AP Biology free-response: best performance was on Q1 (allele frequencies), followed by Q5 (obligate mutualism).
　　Ppoor performance on Q7 (chr ~66% earned 0 pts) & Q8 ( ~50% earned 0 pts).
　　Trevor's Comments：AP US History students/teachers have perhaps achieved biggest score increases of any subject so far this yr, also w/25K more students. Wow.
　　On this year’s APUSH DBQ question, ~6,000 students (out of 500,000) earned all 7 ~100,00 students earned 1/7 pts on it.
　　APUSH short answers: highest mean was Q3 (business leaders), and lowest mean was Q1 (immigration) – but similar results across all of them.
　　1 AP US History student, out of ~500,000, earned a perfect score of 130/130 first time we have seen that achievement in many years.
　　Trevor's Comments：AP Psychology scores remained quite similar, even as 20,000 more students gained access worldwide, a testament to good teaching & learning.
　　In the multiple-choice section, AP Psychology students earned highest means on social/developmental psych, lowest on abnormal behavior.
　　Students fared much better on Q2 (learning/cognition) than Q1 (sensation/perception):spr.ly/6015BQ6GT
　　1 student, out of ~300,000 so far, has earned all 150/150 points on this year’s AP Psychology Exam. Can’t wait to find out who / where…
　　Trevor's Comments：AP Macroeconomics continues to see score increases: the % of 3,4,5s is higher than 5 years ago & 50% more students are participating.
　　Students did extremely well on multiple-choice, es most challenging were the financial sector questions.
　　More than a third of the students aced this FRQ3 on specialization & trade, earning all 5 pts possible: secure-media.collegeboard.org//digitalServices/pdf/ap/ap16_frq_macroeconomics.pdf. More than 40% of the students found FRQ2 on loans/demand deposits extremely difficult, earning 0 pts:spr.ly/V
　　28 students worldwide (out of 135,000) earned all 90 points possible on this year’s AP Macroeconomics exam.

& 安卓系统连接Ad-hoc无线热点网络教程
安卓系统连接Ad-hoc无线热点网络教程
15:40|编辑:棠梨|来源:265G安卓网
无线网络 有AP和Ad-hoc。
AP(无线访问接入点)是广播式的，安卓系统支持。无线路由器和带AP共享的手机均可搭建AP网络。 (带AP的安卓手机：设置---无线和网络---绑定与便携式热点)
Ad-hoc(点对点)是P2P的连接，安卓系统默认不支持。而多数手机通过Wifi搭建的无线网络正是Ad-hoc。
Wifi 手机带A1上网，先要实现A1支持Ad-hoc
有两种方法:
一是安装Ad-hoc补丁，补丁受限于终端设备和系统版本，并不通用。
二是通过软件ZT-180实现。成功后每次运行ZT-180即可连接手机，并不比通常打开自带WIFI联网麻烦多少。这方法最大优点是全安卓平台通用。
【教程如下】
1. 手机安装无线热点软件。进入软件，设置即将搭建的Ad-hoc网络名称(比如123)
2. A1取得Root权限
3. A1安装Busybox。打开Busybox ，点击主界面下方Install。出现Status：Done!即可退出
4. A1自带 Wifi 确认开启。手机端 无线热点网络 确认开启
5. A1安装ZT-180 Adhoc Switcher 。打开ZT-180 ，显示已获得最高权限，黑屏约5秒
Continue & Continue &Settings & SSID for Adhoc mode
输入步骤1中设置的网络名称(比如123)
【如果使用WEP加密:勾选 Use WEPencryption WEP，点Set WEP Key输入WEP密钥】
返回主界面，点Try to Switch to Ad-hocmode,just to try... 等待... 直到图像显示平板和手机成功连接
【重新使用AP网络：点Switch to Infrastructure mode 即切换到AP模式。否则在Ad-hoc模式下直接连路由器容易出错】

265G推荐游戏Android AP是什么意思_百度知道
Android AP是什么意思
我有更好的答案
APP指的是智能手机的第三方应用程序。比较著名的应用商店有苹果的App Store，谷歌的Google Play Store，安智市场，还有黑莓用户的BlackBerry App World，微软的Marketplace等。
最近两年，app分发成为各大互联网巨头的新“行当”，在手机厂商和专业应用下载平台的夹击下，不但没有被挤成“夹心饼干”，反而成了可口的“驴肉火烧”。以百度手机助手为例，其打破传统应用分发的下载套路，从娱乐和社交的角度去“再造”应用分发平台，开创了一个值得圈点的应用市场新模式，也可以看到APP快消化品牌运作的趋势。

Android AP?是Android API吗
Android AP是干什么的？
AP应该是指无线访问接入点Android AP 应该就是Android 下的无线访问接入点
本回答被网友采纳
把网络共享给别的电脑，手机，用手机发射无线信号了。andorid 系统的 无线AP 。 可以用自己的手机上网 无线AP（Access Point）即无线接入点。然后作为wifi
无线接入点，它是用于无线网络的无线交换机，也是无线网络的核心。无线AP就是WIFI热点
这个意思就是说：使用安卓的手机操作系统。利用手机能够上网的这个功能进行延伸。达到的效果就是将这个安卓手机的网络以wifi的形式共享给其他无线网设备。
“Android”是一种以Linux为基础的开放源码操作系统，主要使用于便携设备。目前尚未有统一中文名称，中国大陆地区较多人使用安卓（非官方）或安致（官方）。Android操作系统最初由Andy Rubin开发，最初主要支持手机。2005年由Google收购注资，并拉拢多家制造商组成开放手机联盟开发改良，逐渐扩展到到平板电脑及其他领域上。 2010年末数据显示，仅正式推出两年的操作系统的Android已经超越称霸十年的诺基亚Symbian系统，跃居全球最受欢迎的智能手机平台。Android的主要竞争对手是苹果的IOS，微软的WP7以及RIM的Blackberry OS。“AP” 即 无线AP（Access Point）无线接入点，它是用于无线网络的无线交换机，也是无线网络的核心。无线AP是移动计算机用户进入有线网络的接入点，主要用于宽带家庭、大楼内部以及园区内部，典型距离覆盖几十米至上百米，目前主要技术为802.11系列。大多数无线AP还带有接入点客户端模式（AP client），可以和其它AP进行无线连接，延展网络的覆盖范围。 “Android AP” 就是Android 统统下的应用的无线访问接入点模式。
相当于把你的手机变为一个wifi路由器。
就是可以在手机上实现无线路由功能
