Eliminate render-blocking JavaScript and CSS in above-the-fold content

Your page has 6 blocking script resources and 3 blocking CSS resources. This causes a delay in rendering your page.

Leverage browser caching

Setting an expiry date or a maximum age in the HTTP headers for static resources instructs the browser to load previously downloaded resources from local disk rather than over the network.
Leverage browser caching for the following cacheable resources:

Prioritize visible content

Your page requires additional network round trips to render the above-the-fold content. For best performance, reduce the amount of HTML needed to render above-the-fold content.
The entire HTML response was not sufficient to render the above-the-fold content. This usually indicates that additional resources, loaded after HTML parsing, were required to render above-the-fold content. Prioritize visible content that is needed for rendering above-the-fold by including it directly in the HTML response.
Only about 51% of the final above-the-fold content could be rendered with the full HTML response.
Minify JavaScript

Compacting JavaScript code can save many bytes of data and speed up downloading, parsing, and execution time.
Minify JavaScript for the following resources to reduce their size by 41KiB (36% reduction).
Minifying http://code.jquery.com/ui/1.11.4/jquery-ui.js could save 40.1KiB (36% reduction) after compression.
Minifying http://www.blackboard.com/static/v-504911052000000000/jquery.lazyload.js could save 938B (41% reduction) after compression.
Enable compression

Compressing resources with gzip or deflate can reduce the number of bytes sent over the network.
Enable compression for the following resources to reduce their transfer size by 28.7KiB (67% reduction).
Compressing http://ml314.com/tag.aspx?842017 could save 14.5KiB (62% reduction).
Compressing http://js.acq.io/ATRK_B956AD90_min.js could save 14.2KiB (73% reduction).
Optimize images

Properly formatting and compressing images can save many bytes of data.
Optimize the following images to reduce their size by 5KiB (19% reduction).
Compressing http://www.blackboard.com/static/v-636282083432593654/img/home-sprite_3.png could save 2.1KiB (12% reduction).
