Study & grades
Study & grade calculators
Everything a student reaches for in one place: a CV maker for your first job; your marks percentage, semester GPA and cumulative CGPA worked out the way institutions calculate them; and maths helpers that solve equations, fractions, matrices, statistics and probability step by step.
There are also tools for the work around studying: a citation generator for APA, MLA and Harvard, a Pomodoro focus timer, an exam countdown and a study planner. Grade scales differ between universities, so the GPA tools use the common 4.0 scale — check yours if it differs. Everything runs in your browser.
