# For the Student

### What is a student's account

A student's account is a subscription account giving full access to the MathLynx functionality available for students.   This includes full access to all of the MathLynx online interactive library and all associated tools, plus full functionality of all walk-through tutors, randomly generated practice sessions (with immediate feedback), and scored evaluation sessions (with delayed feedback).   Student account holders have the ability to examine all of their records and review progress, register for classes offered by instructors using MathLynx, and grant instructors the ability to review progress history data.

### How to get an student's account

To obtain an student's account with MathLynx, first create an account (click here).   You will then need to subscribe.   MathLynx offers monthly, semi-annual and annual rates.

### How to register for a class

Once you have an account and wish to register for a specific class, you will have to inform your instructor and give them your user id.   The instructor then admits you.   This admission is not something you can do on your own.

### How to view course-specific content

Supposing that we have been admitted to Sample Course 1, to view course-specific content select Your classes under the STUDENT tab in the header menus.   You will be redirected to a page on which you must select Course Reports, as indicated.

Once at Course Reports, you will find a drop-down selection tool which allows you to find all MathLynx courses into which you have been admitted.   This is shown in the following two images.   To see content for Sample Course 1, we select that item.

By selecting the desired course, here Sample Course 1, we will see all of the active pages for that class.   Note that page Evaluation: Perpendicular Bisector of a Segment allows for two attempts over a bounded time window.

### How to type mathematics

Typing mathematics is awkward work.   There is no universal agreement on many notations, and choices have to be made to render communication with our mathematics engine manageable.   As a result we have incorporated several rules, which are described below.

The four main rules you should keep in mind are the following.
1. Functions written using parentheses about the input.   Thus   $\sin(x)$   rather than   $\sin\, x\;$ .
2. Multiplication should be written using the symbol   "$\cdot$" .   Thus   $x\cdot y$   rather than   $xy$   or   $x\, y\;$ .
3. Multiplication should be written with the exponent following the base as superscript.   Thus   $\sin(x)^2$   rather than   $\sin^2x$   or   $\sin^2(x)\;$ .
4. When in doubt, use parentheses:   $\left(\sin(x)\right)^2$   works well.

Click here to practice typesetting mathematics.   You will be able to see how your entry is represented by our editor.   Functions should generally be chosen from the palette obtained from the hot-spot on the right of the editor.   Output should be examined for whether or not it corresponds to the desired.   It is worth familiarizing yourself with this page, as you can cut-and-paste from it to other math boxes throughout the site.

### What are evaluations?

Evaluations are scored (from 0 to 1) problems which can be used for either self or in-class assessment purposes.   Here we follow Student1 taking Evaluation: Find Equations for Lines from Geometric Data by accessing it through the text, and Evaluation: Perpendicular Bisector of a Segment from within the course content of Sample Course 1.   In the first case, Student1 accesses the evaluation through the text, completes the content-boxes, and clicks on "SUBMIT".   In the second case, Student1 accesses the evaluation through the content of Sample Course 1, completes the content-boxes, and clicks on "SUBMIT".

#### Evaluation through text

Student1 finds Evaluation: Find Equations for Lines from Geometric Data in the library.

Clicking on the title opens the page.   Student1 completes the input features of the page and clicks "SUBMIT".

The work is instantly graded and a score is given.

#### Evaluation through course

Student1 finds Evaluation: Perpendicular Bisector of a Segment in the posted pages of Sample Course 1.

Clicking on the title opens the page.

Student1 completes the input features of the page and clicks "SUBMIT".   Again, the submission is instantly graded and a score is given.

Now, however, on viewing the posted pages of Sample Course 1, Student1 has only one attempt left at Evaluation: Perpendicular Bisector of a Segment.

### How to view personal records

To view any submitted evaluations, select Your evaluations under the STUDENT tab in the header menus.   You will be redirected to Evaluation Report where you will see all evaluations you have completed.   Note that each entry indicates whether or not the evaluation was completed within a class, the date and time completed, and whether or not the score has been edited.   (If taken within a class the instructor can edit the score.)

To view a specific evaluation, simply click on that evaluation.   For example, to view "Find Equations for Lines from Geometric Data" simply click on those words.   You will be redirected to an uneditable reproduction of your submission, showing your entries and scores.
