studying outside the UK. Comparable in content and standard to the UK A Level, it offers a modular structure that gives international students flexibility over when and how they sit their exams &#8211; with assessment windows in January, June and October each year. Whether you are aiming for the full IAL or the standalone International Advanced Subsidiary (IAS), this page covers everything you need to know about the qualification, its structure, and what each unit involves.\n          <\/p>\n\n          <div class=\"ols-ial-hero-actions\">\n            <a class=\"ols-ial-btn\" href=\"https:\/\/www.onlinelearningsystem.net\/xyz\/shop\">View Courses<\/a>\n          <\/div>\n        <\/div>\n\n        <div class=\"ols-ial-info-panel\" aria-label=\"Edexcel International A Level Chemistry overview\">\n          <div class=\"ols-ial-info-item\">\n            <h2>Two Qualifications, One Specification<\/h2>\n          <\/div>\n\n          <div class=\"ols-ial-info-item\">\n            <h2>International Advanced Subsidiary (IAS)<\/h2>\n            <p>\n              The IAS consists of Units 1, 2 and 3.
