Elementary students spend years trying to master arithmetic. Teens struggle with the shift to algebra and its use of variables. High-school students must face diverse challenges like geometry, more advanced algebra, and calculus. Even parents experience frustration as they struggle to recall and apply concepts they had mastered as young adults, rendering them incapable of providing math help for their children. Whether you need top Math tutors in Boston, Math tutors in Detroit, or top Math tutors in Dallas Fort Worth, working with a pro may take your studies to the next level. The truth is, everyone struggles with math at one time or another. Students, especially at the high-school level, have to balance challenging coursework with the demands of other courses and extracurricular activities. Illness and school absences can leave gaps in a student’s instruction that lead to confusion as more advanced material is presented. Certain concepts that are notoriously difficult to master, such as fractions and the basics of algebra, persist throughout high school courses, and if not mastered upon introduction, can hinder a student’s ability to learn new concepts in later courses. Even students confident in their math skills eventually find a course or concept incomprehensible as they reach advanced math classes. In other words, no matter what your age or ability, everyone eventually needs help with math. Varsity Tutors offers resources like free Math Diagnostic Tests to help with your self-paced study, or you may want to consider a Math tutor. Varsity Tutors is happy to offer free practice tests for all levels of math education. Students can take any one of hundreds of our tests that range from basic arithmetic to calculus. These tests are conveniently organized by course name (e.g. Algebra 1, Geometry, etc.) and concept (e.g. “How to graph a function”). Students can select specific concepts with which they are struggling or concepts that they are trying to master. Students can even use these concept-based practice tests to identify areas in which they may not have realized they were struggling. For instance, if a student is struggling with his or her Algebra 1 course, he or she can take practice tests based on broad algebra concepts such as equations and graphing and continue to practice in more specific subcategories of these concepts. In this way, students can more clearly differentiate between those areas that they fully understand and those that could use additional practice. Better yet, each question comes with a full written explanation. This allows students to not only see what they did wrong, but provides the student with step-by-step instructions on how to solve each problem. In addition to the Math Practice Tests and Math tutoring, you may also want to consider taking some of our Math Flashcards. Varsity Tutors’ Learning Tools also offer dozens of Full-Length Math Practice Tests. The longer format of the complete practice tests can help students track and work on their problem-solving pace and endurance. Just as on the results pages for the concept-specific practice tests, the results for these longer tests also include a variety of scoring metrics, detailed explanations of the correct answers, and links to more practice available through other Learning Tools. These free online Practice Tests can assist any student in creating a personalized mathematics review plan, too, as the results show which of the concepts they already understand and which concepts may need additional review. After reviewing the skills that need work, students can take another Full-Length Math Practice Test to check their progress and further refine their study plan. Once a student creates a Learning Tools account, they can also track their progress on all of their tests. Students can view their improvement as they begin getting more difficult questions correct or move on to more advanced concepts. They can also share their results with tutors and parents, or even their math teacher. Create a Varsity Tutors Learning Tools account today, and get started on a path to better understanding math!

Review Kelebihan dan Kekurangan Samsung Galaxy J2 Prime (Dipakai Sekarang)

Galaxy J Prime series merupakan perangkat yang dihadirkan oleh Samsung untuk pasar di Indonesia. Kebetulan  jenis smartphone ini merupakan smartphone pertama yang admin gunakan, sehingga pastinya admin lebih tahu dari orang yang belum memakainya. Mungkin juga, dari review ini, bisa jadi sebagai bahan pertimbangan bagi Kamu yang ingin atau sedang mencari tahu apa kelebihan atau kekurangan  smartphone ini.

Admin membeli HP Samsung Galaxy J2 Prime ini di salah satu toko di daerah tempat tinggal admin. Di dalam dus kemasan dari smartphone ini berisi kepala charger (adaptor), kabel USB, kartu garansi, earphone, satu buah baterai, dan pastinya hape itu sendiri. Menurut referensi yang admin baca kalau dari segi fisik, sekilas desain bagian depan dari hape ini mirip-mirip dengan hape Samsung Galaxy Y Duos generasi pertama. Hanya saja, hape ini nampak memiliki sebuah lampu flash di bagian depan yang terletak di atas layar. Selebihnya, ia tampil tak jauh beda dengan hape yang dimaksud tadi, lengkap dengan tombol home fisik khas Samsungnya.

Jujur saja ya, pertama kali membeli hape tersebut, tidak terlalu memikirkan soal desainya, admin lebih memikirkan apakah HPnya bisa digukan untuk nge-blog atau tidak. Hape ini belum dilapisi dengan pelindung, sehingga harus beli pelindung layarnya dan kondom hapenya biar gak kotor atau kalau jatuh biar lebih aman.

Bagian belakang Samsung Galaxy J2 Prime terbuat dari bahan semacam plastik berpola yang mirip dengan milik Galaxy S5, dan covernya ini juga sangat mudah kotor ketika dipegang jadi memang harus beli lagi pelindung layarnya. Tapi, secara keseluruhan, hape ini terbilang nyaman untuk digenggam.

Ukurannya yang tergolong agak kecil (layar 5.0 inch) membuatnya mudah untuk digunakan dengan penggunaan satu tangan. Di bagian belakangnya itu kita akan menemukan sebuah kamera yang agak menonjol dan memiliki list atau frame dengan finishing chrome, serta lampu LED flash dan juga lubang speaker di sisi kiri dan kanan kameranya. Cover belakangnya bisa dilepas dan baterainya juga bisa dilepas. Dibalik covernya, kita bisa menemukan dua slot kartu micro SIM dan juga slot microSD yang terpisah.

Kedua SIM nya ini sudah bisa terkoneksi di jarinya 4G LTE yaa. Sementara untuk tombol volume diletakkan di sebelah kiri, dan tombol power di sebelah kanan. Bagian atas terdapat lubang jack audio 3.5mm, sementara di bagian bawah ada port microUSB v2.0 untuk charging.

Kembali ke tujuan inti saya membeli hape, yaitu hanya untuk membantu mengelolah blog dan urusan kerjaan gitu, jadi yang pertama dicari tahu itu masalah apakah support jaringam 4G dan aplikasinya apakah bisa berkomunikasi secara lancar.

Kalau dilihat sekilas, hape ini nampak tak memiliki banyak aplikasi bawaan. Namun kalau dilihat lebih dekat, ternyata beberapa aplikasi bawaan yang disimpan dalam folder untuk membuatnya seolah-olah hanya membawa sedikit aplikasi. Disini, kita bisa menemukan beberapa aplikasi dasar seperti kontak, gallery, kamera dsb. Sebagai tambahan, Samsung juga telah memberikan “bonus” aplikasi dari Microsoft termasuk Word, Excel, PowerPoint, OneDrive, OneNote, dan Skype. Dan tentu saja, aplikasi Google juga ada dong! Plus, aplikasi dari Samsung sendiri juga sudah terinstal pada smartphone dengan bentang layar 5.0 inch ini. Sebagian besar diantaranya mungkin bakal berguna, tapi beberapa yang lain kemungkinan hanya akan dibuka oleh pengguna sekali atau dua kali saja.

Salah satu apps bawaan Samsung yang sering admin pakai adalah Samsung Notes untuk mencatat beberapa informasi yang penting, misal tanggal berapa saja saya sudah ganti oli motor hehe. Sebuah fitur untuk mendukung performa atau mengatur perawatan perangkat juga sudah disediakan oleh Samsung pada smartphone ini, yang artinya bakal menjadi poin plus lain bagi hape low-end ini. Fitur Device maintenance ini bakal sangat berguna bagi kita untuk memantau “kesehatan” perangkat, mulai dari baterai, penyimpanan, RAM, hingga keamanan terhadap program jahat. Fitur ini bakal sangat membantu dan saya cukup sering memanfaatkan fitur ini untuk membersihkan data tak terpakai yang tersimpan di hape. Yang terakhir, aplikasi bawaan yang (mungkin) juga bakal berguna adalah aplikasi Secure Folder (Folder aman).

Samsung Galaxy J2 Prime dibekali dengan chipset MediaTek MT6737T yang punya CPU Quad-core 1.4GHz Cortex-A53 64-bit, GPU Mali-T720MP2, serta dukungan RAM 1.5GB. RAM nya yang tergolong tanggung tersebut dapat bekerja dengan baik dan mampu memberikan pengalaman berpindah apps yang mulus. Tapi, karena keterbatasan kapasitasnya itu, terkadang beberapa aplikasi harus dibuka atau dimuat ulang khususnya ketika mencoba untuk membuka dan me-minimize lebih dari 4 aplikasi. Harap maklum, gejala lemot ketika mencoba menggunakannya untuk ber-multitasking hampir tidak terasa. Hal yang paling bisa dibanggakan dari hape ini selain tentunya brand “Samsung” nya adalah bagian baterai. Untuk hape dengan layar 5.0 inch, kapasitas baterai 2600 mAh memang tergolong besar banget. Apalagi resolusi layarnya cuma qHD, plus menggunakan prosesor hemat daya.

Sementara untuk pengisian daya baterainya, Samsung membekali hape ini dengan adapter daya dengan output 5.0V – 1A. Pengisian daya dari sekitar 10% ke 100% dalam keadaan hape dimatikan atau dinyalakan sama-sama membutuhkan waktu kurang lebih 2 jam 40 menit.

Kesimpulan dari admin: Hape ini ringan untuk dipakai jika hanya sekedar bersosial media, tetapi tidak cocok dipakai buat kerja. Kalau menurutmu bagaimana? Berikan komentarmu! Berikut ini adalah harga terbaru dari Samsung Galaxy J2 berdasarkan hasil pencarian di Bukalapak.
